Can anyone suggest ways of debugging this?

Run coredumpctl to see what processes crashed. There should be at least a gnome-shell crash, maybe also a gnome-session crash, maybe also an XWayland crash. Usually only the gnome-shell and gnome-session crashes are interesting. Use 'coredumpctl gdb' to get backtraces for each crash in gdb. Be sure to install the debuginfo via the dnf command that gdb will suggest and then restart gdb each time, to get a high-quality backtrace.

Once you have a backtrace, you have all you need for a quality crash report. Skip Red Hat Bugzilla and go straight to upstream for best results. The gnome-shell crash should be reported at https://gitlab.gnome.org/GNOME/gnome-shell/issues (yes, it's a new issue tracker, I'm afraid you just missed being first!). If there's also a gnome-session crash, that should be reported at https://bugzilla.gnome.org/enter_bug.cgi?product=gnome-session.

Hope that helps,

Michael
