Additional info:
Comment 1 Stepan Broz 2020-11-14 11:31:17 UTC 
Reproduced, crashes for me reliably too.
Comment 2 Luya Tshimbalanga 2020-11-14 18:49:43 UTC 
Known issue from upstream seemly caused by Alembic,
- https://developer.blender.org/D7703
- https://developer.blender.org/T75436
- https://developer.blender.org/T75252

Would someone reproduce the problem on a non-AMD hardware?
Comment 3 Stepan Broz 2020-11-16 12:43:30 UTC 
It crashed for me on an Intel (CPU + integrated GPU).
Comment 4 Andrea 2020-11-16 13:17:58 UTC 
For me it crash also on:

Comment 5 Phil Weber 2020-11-16 22:38:06 UTC 
I've had the problem as well and have the feeling that the current Blender requires Python 3.7 as opposed to 3.9. The bug can be replicated by deleting and then reinstalling Blender and with the new blender, change the preferences as they come up. There will be a crash.
Comment 6 Luya Tshimbalanga 2020-11-17 02:18:22 UTC 
One of key issues:
"LLVM triggered Diagnostic Handler: Illegal instruction detected: VOP* instruction violates constant bus restriction
renamable $vgpr4 = V_CNDMASK_B32_e32 32768, killed $vgpr5, implicit killed $vcc, implicit $exec
"
Through investigation, it is related to https://developer.blender.org/T81835

The choice is either wait for the incoming 2.91 release (https://developer.blender.org/project/view/117/) or look through upstream patches.
