Just for the record, I see the same issue with a Dell Precision 7760 (CID 202103-28858) when running 22.04 beta on Wayland. I was told the HDMI connector was wired directly to the Nvidia GPU, so gnome-shell crashes when I connect an external monitor there, but even after logging back in, the monitor cannot be used.
Plugging the same monitor to the USB-C connector (which is wired to Intel GPU apparently) works like a charm...
