Bare Metal. I added the nvidia-bug-report.log.gz at my first post.

The logs are from when you’re running nouveau, it has to be created while the nvidia driver is loaded to catch the error.

Ok, here the new logs while the nvidia driver is loaded.

No idea for this error?

Not really.
General options

Thanks. I did the upgrade and removed the xorg.conf.
It looks different. While reboot there is no white cursor, just a black screen but the same error in the log.

I add a new nvidia log report.

Already tried downgrading the driver?
e.g.
apt install nvidia-driver-418
or even
apt install nvidia-driver-390
