I recently upgraded to Lunar Lobster from Kinetic Kudu on a desktop system (HP Victus - AMD Ryzen 7 5700G - Radeon RX 6600XT). Most things are the same or better except Wayland crashes upon suspend/resume or display blank/unlock multiple times a day vs never before, putting me back to a login screen and starting a new session.
I'm unsure offhand how to debug or report as the most annoying aspect of this is that there are no error messages to give me a starting point and Ubuntu itself seems unaware of the problem (i.e., I'm never prompted that there was a "system program problem detected").
I scrolled through journalctl output and the most relevant bits are below (e.g., [email protected]: Main process exited, code=dumped, status=11/SEGV):

And trying to find a core led me to:
$ cat /proc/sys/kernel/core_pattern
|/usr/share/apport/apport -p%p -s%s -c%c -d%d -P%P -u%u -g%g -- %E
$ ls -l /var/crash
total 51148
-rw-r----- 1 mjf whoopsie 52366746 Apr 26 16:11 _usr_bin_gnome-shell.1000.crash
-rw-r--r-- 1 mjf whoopsie 0 Apr 26 16:11 _usr_bin_gnome-shell.1000.upload
-rw------- 1 whoopsie whoopsie 37 Apr 26 16:11 _usr_bin_gnome-shell.1000.uploaded
So it caught one and blamed gnome-shell but never prompted me to send a report, and there have been at least 2 crashes since that timestamp.
