Can you try run
./blender --debug-gpu > gpu_debug_log.txt
from the command line, trigger the bug, and attach the resulting file here.https://docs.blender.org/manual/en/latest/advanced/command_line/launch/linux.html
Most likely it will contain more information about the error.

I'm currently bisecting it... hope to add the offending commit later this evening
I don't think it's a gpu bug. I see a mesh with a bogus number of verts.

Can't reproduce either, but edited report to reflect likely cause
Changed status from 'Needs Triage' to: 'Confirmed'
Because of the depsgraph usage that we found out to be "incorrecct" a few days ago, I'd assume this is a known case where a workable fix is done with D14997 (pending review).
Added subscriber: @PratikPB2123
Cannot repro either. I think it's fair to raise the priority if culprit commit is known (Feel free to revert the priority)
I think it's fine for high priority, we just need someone who's familiar to review
[D14997](https://archive.blender.org/developer/D14997)
:)With nobody able to reproduce it smells like a threading/locking thing... I'll see if I can investigate a bit more.
Hm. It happens in my own build, but not in the daily ;-( so it must be some library problem in my own build maybe? But as the daily runs fine it's probably better to archive this bugreport.

I can crash here - ASAN seems to report at least 2 types of error.

report2.txt
In your own build? or the daily from b.org?
And if your own build do you happen to be on ubuntu 20.04 as well?
Oh no, I see in the report. Windows. That makes it a real thing after all I think. Especially since your crash is in the same spot as mine. I'll upload my crashlog as well.

FYI: got a similar thin in #98359 (Regression: Crash switching to scene with LineArt).
That one I can reproduce (whereas this report I cant)
To me it looks like an access conflict. Let's see D14997
Sadly this doesn't help. With this patch applied it even crashed once on loading the crash.blend file. next time it did load, but still crashed when switching to edit mode.
https://developer.blender.org/D15022 fixes it
