Hi,
I just started recently having this bug after upgrading my PopOS system from 20.09 to 21.04.
It is similar to the one here : # NVIDIA driver crash on kernel 5.11.2 driver version
Here is the nvidia-bug-report.log.gz file, I could not run past the X11 server on my machine, the screen does not load the gdm login manager. By plugging another screen in HDMI I got to the login screen, I ran the tool without the X11 server running, I logged in inside the tty.
