In Fedora 38, logging out of GNOME can quite often cause a crash. The crash doesn’t have any real negative consequences, but you will likely get a crash notification the next time you log in. This behaviour is known and you can safely just ignore or dismiss the notifications; we have sufficient data on the crashes to work on fixes.
There are likely several different but similar causes in play here. The technically-included can find more details in the upstream reports (1, 2) and proposed fixes (1, 2).
Bugzilla report: #2180277
Just ignore and/or dismiss the crash notifications.
