Inventor random crashes due to Microsoft.NETCore.App\8.0.12\coreclr.dll

[b_sh]

Hello,

For months not a co-worker has had issues with Inventor crashing without warning. There are no popups of crash reports or anything anywhere when Inventor crashes. The only signs of the crash is found in Event viewer it has this logged:

Description: The process was terminated due to an internal error in the .NET Runtime at IP 0x00007FF82867D390 (0x00007FF828580000) with exit code 0x80131506.

I've lost track of things we have tried but now we have:

- Replaced the 3dX mouse he was using.

- Replaced the entire computer after trying different troubleshooting steps on his other computer.

- Updated and rolled back .Net versions and graphic drivers.

There are probably many more things I've forgotten over the months, but does anyone have any ideas as to what can be causing this?

Hi! The behaviors do not sound right to me. Please make sure all critical Windows updates are installed and the graphics driver is updated. Go to the PC vendor site and install all critical updates applicable to your PC.

Use Microsoft Disk Cleanup to remove cached files.

Go to Control Panel -> System -> Advanced System Settings -> Environment Variables -> on either panel, add "INV_ENABLE_WER_SUPPORT" and set it to 1.

Right-click on Inventor desktop icon -> Properties -> Compatibility -> check "Run as Admin" and go to "Change High DPI settings" -> check both boxes.

Does it work better afterwards?

Many thanks!

Thanks, I've made these changes to the desktop will report back any findings.

An idea I've had is that his main monitor is a 45" "TV", have you seen Inventor crashes due to the monitor used before?

Hi! I have heard instability due to mismatched resolutions between two displays. Please make sure the two displays are using the same resolution settings. Also make the one hosting Inventor the primary display.

Many thanks!

Hello @johnsonshiue,

So we did just crash again, but this time we finally got an error report to send thanks to the environment change made. The report id is 800158226, do you see anything in this file that might help pinpoint what's causing the issue?

[johnsonshiue]

Hi! I have located the crash report but I am clueless. The report is incomplete. I don't know what happened. Here are my suggestions.

1) Make sure all critical Windows updates are installed and the graphics driver is updated.

2) The Intel Gen 13 CPU has a general stability issue due to high voltage. Intel has been working with PC vendors to publish updates. Please go to PC vendor site and install all critical updates to your specific machine. 

3) Install the latest Inventor update to your Inventor release (the report did not show which release you are on due to incomplete data).

4) Run Regedit.exe and find the following two registry keys. Change the value to 1000000.

"Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\USERPostMessageLimit"

 "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\GDIProcessHandleQuota"

Many thanks!

[b_sh]

I will make these changes tomorrow. The reason for the incomplete logs might be the error with .net, from my understanding this error code causes the app to just shut down with no warning. So might be shutting down before a log can be completed. Will come back once ive made these changes and seen any possible results. Thanks

[b_sh]

Hello again,

Made the changes above now, there was no new updates but here is the Inventor version info: 

Built: 293, Release: 2025.2.1

Autodesk Inventor Professional 2025

I've also emailed you the minidump file that was created, titled "Minidump file for crash report id 800158226"

[b_sh]

The user should have sent an crash report today after the changes was made. Do they look better now?

Thanks

[johnsonshiue]

Hi Benjamin,

The new reports point to a known issue INVGEN-83127. The latest status shows the project team is working on a fix but the fix has not yet been finalized or released.

Many thanks!

Question... Do you use Large Icons or thumbnails?  

We are having one user with the same crash of: 

C:\Program Files\Autodesk\Inventor 2025\Bin\Inventor.exe
C:\Program Files\dotnet\shared\Microsoft.NETCore.App\8.0.12\coreclr.dll

I just realized one difference in his machine is he uses large icons as a default windows explorer setting. A google search (not even mentioning Inventor) resulted in a link to this issue. Might be unrelated but I thought I'd throw it out there. 

Inventor crashes explorer when showing thumbnails - Autodesk Community

[b_sh]

This is an interesting observation, I will have a look on Monday and see if that's the case. But his computer is brand new (after changing it once before already) so I doubt he went out of his way to change that already. But will check just to be sure.

[kbear2AYYK]

Oh how i hate to say this but I'm grateful you are having issues too! (Misery loves company!)

We've been dealing with this since June of last year. We went as far as buying a brand new computer to eliminate the excuse and blame of the system (although it's still what autodesk is blaming). Check this out 

• 06-2024 We tried many autodesk recommendations in an attempt to eliminate this issue
• The issue remained
• Coreclr.dll is always the related cause to the error 
• 08-2024 We rebuilt the original PC to factory defaults in an attempt to eliminate this issue.       
• The issue remained.
• 10-2024 We bought a completely new PC in an attempt to eliminate this issue.
• The issue remained.
• 1-21-2025 We rebuilt his original machine and switched back but this time we did not install the 3DConnexion Mouse nor and Adobe products in an attempt to eliminate this issue.
• 1-24-2025 Inventor ran without crashes for 3 days. The user ran a script to eliminate the new windows context menu. Inventor crashed. We assumed it was the cause so...
• 1-26-2025 We restored a system image from 1-20-2025
• Inventor is still crashing 
• Autodesk is still blaming the system... The most resent request of asking us to swap computers.
• Bang head on desk 

[b_sh]

Trust me I'm happy to hear that I'm not alone in having this issue, we have banged our head on the desk multiple times over the past three or four months, and our vendor has been like this is an issue we haven't seen before. We have tried all the same steps as you guys. The user has reported not crashing when running Inventor on a co-workers laptop and when the other co-worker tested his machine for a few days they did not crash at all... But this brand new machine with slightly different GPU is also crashing.... We also thought 3DConnexion was the issue to begin with, but we bought him a new mouse to begin with, did not help, had theuser use it without any mouse or software, still the same. Not sure what to do at this point as its clearly an issue with Inventor. I can recommend trying the regedits and changes mentioned prevously if you're not getting crash reports, now we at least get crash reports.

I asked them for extended log files. Autodesk says this is not possible because if they did, the logs would reveal proprietary details. Ok... But a quick Google search was able to reveal that encryption of log files is not only possible... but commonplace. So hopefully they implement this feature soon.

The company i was with used Siemens NX. It had log files that were incredible... I could just open the past three crashes, see the line of code it crashed on, and they would fixed it (usually in less than a month). 

For thousands of dollars per year, per seat... I expect better from autodesk.

What specs is the user running on their current computer? My coworker did no have these issues before  we upgraded his PC, but started after the fact, but then again he was not on 2025 version of Inventor before he got a new computer. He now has a ThinkStation P3 Tower model 30GS008UMT with
Intel core i7-13700k, 32GB of DDR5-440 RAM, RTX 4000 Ada Gen. 20 GB

[kbear2AYYK]

After 8 months, I feel I am on my own with this issue.. 

Something new I am doing is looking at the extended log files ("INV_ENABLE_WER_SUPPORT" = 1)
c:\users\~user~\AppData\Local\Autodesk\CER

There is a dmp file in there. I just found out we can view it by downloading WinDbg

Link :  Install WinDbg - Windows drivers | Microsoft Learn

In that file I found:

WARNING: Unable to verify timestamp for FwUI.dll
Failed to request MethodData, not in JIT code range

Googling just that line came up with nearly 20 results from forums.autodesk.com alone

I am no programmer so a lot is Greek to me. What I am hoping to find is the common denominator beyond simply a simple coreclr.dll error.  The dump file is more complete than Windows Event Viewer can show but still stops short of saying what called the error or what line crashed Inventor. 

Also, similar specs but Dell
Intel(R) Core(TM) i7-14700
96 GB RAM

RTX 2000 - 16 GB

Hi! This is still work in progress. Based on what I heard from the project team, the crash could be .Net Core related. So far we have three known crashes (INVGEN-78934, INVGEN-82194, and INVGEN-83127). The first two have been resolved on internal builds targeting the coming 2025.3 update. The last one is still being investigated.

Please feel free to escalate these issues with Autodesk Product Support and mention above defect IDs.

Many thanks!

Same problems here.  2 month old HP ZBook Power 16 inch G11, all updates to both Windows 11 Pro and Inventor 2025 applied.  Any updated news on a potential fix?

Hi! While the issues are still being investigated (some may have been fixed in the coming updates), there is another setting to look at. Recently, I was made aware of a Windows setting could interrupt how an application performs computing tasks. Launch Regedit and go to the following registry key. Change it to 0.

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy

FIPS setting: https://learn.microsoft.com/en-us/windows/security/security-foundations/certification/fips-140-valid...

Whether or not it can be turned on or off depending on your organization. You will need to consult your IT team.

Please let me know if Inventor behaves more stably after the change.

Many thanks!
