Hi @JoelMckone 

Thanks a lot for posting your question to the forums!  

Try the following solutions to resolve this behavior. Test AutoCAD after each.

Install the latest updates for AutoCAD

Install the latest AutoCAD updates. Downloads are available in the Autodesk Account in the Product Updates section.
Note: For 2018 versions, make sure to install also the Autodesk License Service (x64) - 5.1.5 Hotfix.

Install the latest Windows updates

Make sure that your version of Windows has all the available updates provided by Microsoft.

Update the graphics cards drivers and configure your graphics settings

Check Autodesk Certified Graphics Hardware to see if the current video card installed in the machine is listed there.

If it is, install the video drivers mentioned in the list, otherwise, try installing the latest graphics driver available from the specific card manufacturer's website. 
If you are using a laptop with a dual graphics card, make sure to configure the software to use the high-performance graphics card. See How to configure Autodesk software to use high-performance graphics.

Consider also Starting AutoCAD without hardware video acceleration.

Update Microsoft .NET Framework

Check the Microsoft .NET Framework Download Page for the latest recommended version.
Download and install it to see if it helps with the crashing.

Install the Autodesk License Hotfix (versions 2014/2015)

Install the Autodesk Licensing Hotfix - POODLE SSL v3 vulnerability (CVE-2014-3566) to potentially resolve any errors when launching.

Confirm that the LAN and firewall settings are correct

1. Go to the Windows Control Panel and search for "Internet Options."
2. Select the "Connections tab."
3. Click "LAN Settings."
4. Deselect all options.
5. Go to Windows Firewall.
6. Be sure the necessary Autodesk URLs and protocols are white-listed. See Which URLs/Protocols need to be white listed for Autodesk subscription Licenses.

Reset AutoCAD to default

Use the following guide to reset AutoCAD to default settings: How to reset AutoCAD to defaults

If the problem persists, continue to troubleshoot using the solutions in AutoCAD randomly crashes or freezes.
Perform a Clean Uninstall to resolve an improper or corrupted installation. 
 
We look forward to hearing back from you with more information so we can help you as a community!

Checked updates and Autocad LT 2023 is up to date.  I suspect it is likely a bad install as Autocad LT 2022 is functioning properly.  Probably best to do a clean uninstall/reinstall and see if that works before checking all the other possibilities.

@JoelMckone your initial post, as it is, means nothing to anyone trying to give you help beyond the basics already covered.

Ideal info to share for such posts here for others to help you include:
1) Is the crash at startup?
Or
2) is it triggered by opening a specific file? All files? some files?
Or
3) is there a specific command that trigger it? and which one?
4) can you get this error to pop-up each and every time on demand?
5) how does everyone else way over here replicate it?

I see you finally got round to listing your LT version: what about your OS?

TIA
