I just started noticing this same error/bug when using 5.15.0-41-generic. I am able still to boot using this kernel, however it is very slow and when it does boot the screen resolution is stuck at 800x600 and the Nvidia drivers do not work (according to nvidia-smi).
On the other hand if i boot with 5.13.0-30-generic, everything is normal, as far as i can tell.
