Blender 4.0.1 doesn't start

Blender got a rebuild, try again now.
It seems to be a problem with blender, openshadinglanguage and AMD GPUs, check the discussion here:

you can try with the AMDGPU PRO drivers, to check if this resolves the matter:
https://wiki.archlinux.org/title/AMDGPU_PRO
and run it like this:
progl blender
or update to latest branch of openshadinglanguage and rebuild blender from source
or wait for the maintainers to provide an updated solution.
