Reproduced, crashes for me reliably too.
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?
It crashed for me on an Intel (CPU + integrated GPU).
For me it crash also on: [root@vm33 ~]# lshw -c video *-display description: VGA compatible controller product: Virtio GPU vendor: Red Hat, Inc. physical id: 1 bus info: pci@0000:00:01.0 version: 01 width: 64 bits clock: 33MHz capabilities: msix vga_controller bus_master cap_list rom configuration: driver=virtio-pci latency=0 resources: irq:21 memory:fc800000-fcffffff memory:fda00000-fda03fff memory:fea14000-fea14fff memory:c0000-dffff
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.
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.
