Not a crash, apparently. The screen is failing to update in Wayland sessions:

abr 06 13:55:43 dantian gnome-shell[37489]: Failed to post KMS update: drmModeAtomicCommit: Argument invalide
abr 06 13:55:43 dantian gnome-shell[37489]: Page flip discarded: drmModeAtomicCommit: Argument invalide

To debug it further please add MUTTER_DEBUG=kms to /etc/environment and then attach a new journal log.

Alternatively, as a workaround try adding MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0 to /etc/environment.
