I don't have an idea why this has happened. I was just forced to the login window. Wayland version 1.14.0.

This is your Wayland compositor (i.e. gnome-shell/mutter) crashing, causing all Wayland clients to abort, including Xwayland. Now that gnome-shell/mutter since version 3.26 starts Xwayand with the "-core" command line option (https://bugzilla.gnome.org/show_bug.cgi?id=789086) which forces Xwayland to dump a core file for any FatalError(), that leads to a core dump from Xwayland. But here Xwayland is not the problem, the crash in gnome-shell/mutter is.
Apparently, not a wayland bug. See comments.
