So everything crashed, and this is in the same crash wave as https://bugs.kde.org/show_bug.cgi?id=435406 ? In this case, it is a known bug in Qt that happens when the Wayland compositor (kwin_wayland in this case) vanishes.
Yes. We need the backtrace of the crash in kwin_wayland. Sadly it's a known and unavoidable issue that when kwin_wayland crashes, all apps crash too (see https://bugreports.qt.io/browse/QTBUG-85631) The app crash logs are not useful; all they do is tell us that KWin crashed. But we need to know why KWin crashed. For that, we need a backtrace of the KWin crash itself. You may be able to retrieve it with `coredumpctl`.
