This sounds very unusual.
You should upload an absolute minimum blend file, which does not require any alembic or osl in that case and delete everything else you have uploaded.
I uploaded the Test File with the crash report, after 170 frame crash, GPU Redner works fine

I won’t have time today to check again. When I find time tomorrow, I will try again.

According to the Blender Team it’s a common issue with a 14900k procesor, but at the moment there is no solution for that

Thankfully, those sorts of issue tend to be quite rare. Still very annoying for someone who experiences it!

I hvae a solution now:
I set the CPU’s P-Cores to 56x and it works perfectly.
By default the P-cores are set to 57x, but in the specifications of the CPU they are specified at 5.6 Ghz, so 56x works now.
