Additional info:
I tried a fresh Ubuntu 20.04LTS with default GNome and recent 470.42.01 beta driver as suggested by X11 maintainers.
Also here same effect. Only that Gnome just restarts the desktop without any crash.
Seems to be reproducable when moinotrs and dockingstation have been power cycled.
