Fusion 360 crashes immediately on open after update

fosterkbettin — Wed, 07 Apr 2021 21:36:59 GMT

Hello

The app crashes immediately on launch, never gets to the splash screen or anything after updating to Big Sur 11.2.3.

I tried restarting, uninstalling/reinstalling and then I tried the automatic clean uninstall.

Unfortunately I couldn't get the automatic clean uninstaller to work because it says "You don't have permission to open the application "Fusion 360 Cleaner.app"

I tried a lot of different things to fix the permissions issue, but haven't been able to get it to work yet.

I also tried following the manual clean uninstall, but it didn't fix the problem.

I attached a crash log

Help!

Foster

Hi @fosterkbettin ,

Installation looks good, Looks like this issue is not related to Fusion 360 installation.
Can you try installing fusion again and let me know if it's working.

Hello,

is there a solution for this topic.

I have a new installed Big Sur 11.2.3 and exactly the same problem.

(Fusion 360 worked on my machine with Big Sur (earlier version). The only thing was a new/clean installation of Big Sur)

Regards,

Stefan

Unfortunately when starting the app, it never gets to the point where I see the splash screen. I do get a crash report though after which is nearly the same every time. I have that attached to the original support issue.

I followed the steps, but unfortunately the files listed are not in the specified folders on MacOS BigSur. In fact, I don't think those files are being installed, and I have tried multiple times uninstalling (doing the manual clean install) and them reinstalling.

After doing some research it looks like this issue is related to fusion 360 using the Intel MKL library. Intel MKL does a vendor_id check and if the cpu is not an Intel one, or a supported Intel cpu, it will simply crash on MacOS. I think that this will have to be fixed by the Fusion development team.

I have not figured out a solution yet. I think the problem for me is due to the Intel MKL not working on my system.

I am pretty sure the only way to fix this, is for the Fusion team to add support for other, better math libraries.
