Solved: I had OPTIX checked by mistake for rendering denoising. I guess Blender does not like that. I would like to see a prompted stating “OPTIX checked for CPU rendering” or something better rather than a hard crash though.
Blender 2.90.1 crashes when I hit F12 even with default cube when rendering with CPU.
GPU works, viewport rendering with CPU or GPU works. Only crashes when sending with F12 and CPU.
All works fine with 2.90
CPU is Threadripper 3990x (64 core)
Anyone else get crashes with F12 and CPU rendering?
