Can you verify if the issue is also present on 6.0~rc7-1~exp1?
I expect it does, but it's better to know then to assume.

There have been quite some commit under 'drivers/gpu/drm/nouveau' in kernel 
6.0 and in 6.0.3 there have been several NPE fixes, although they didn't appear 
directly related to your issue.
It could be, but it could also be that there are more.
