Thanks for the update @HarryHarry123 - Is it a clean install?
straight forward update
I have same issue, InstaMAT keeps crashing when creating new project even with simple fbx cube from Blender. MacBook Pro 16" M1 Pro, Sonoma 14.4 Beta (23E5196e). Hope there will be some update soon so I can try it out finally

my current Sonoma 14.3 is the Public Beta not the Developer Beta version
I think the issue is the Sonoma beta, I have a M1 Max at home and have no issues.
Likely the same issue, from your error report, it appears that there are issues in the GL implementation of that MacOS version.
I think the best bet is to report this issue to the MacOS development team at Apple.

With the latest MacOS - Sonoma Beta 14.4 (23E5205c) works fine without crashing

That’s awesome, glad to hear that! Using a beta OS is a rather risky endeavour!
The issue here was using a beta version of MacOS that has regressions in their GPU drivers. The latest MacOS - Sonoma Beta 14.4 (23E5205c) appears to be working fine according to user reports.
However, we do not recommend or endorse running InstaMAT on a beta version of any OS.
