The log in comment #12 seems to mostly match bug 1951786 so maybe try briefly disabling the Ubuntu Dock extension in the 'Extensions' app and then log in again.
If that has not fixed the problem then please repeat the steps in comment #3. Then if you see the same messages as in comment #5 please open a new upstream issue at https://gitlab.gnome.org/GNOME/mutter/issues -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1952766 Title: Disconnecting monitor crashes shell (wayland, gnome) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1952766/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
