() from /usr/lib64/qt5/plugins/kf5/org.kde.kidletime.platforms/KF5IdleTimeWaylandPlugin.so This is perhaps a bit old... ... and while I don't normally follow crash dumps, it looks as if this is failing while looking to see if the system is idle There is a old Bug 433783 that may be related and there have been some work (and reversions) in the area: https://invent.kde.org/frameworks/baloo/-/merge_requests/200

I'm guessing you are stuck on Plasma 5 but it would be interesting to know if you have a Plasma 6 system available and see the same behaviour.
Sorry, I have no Plasma 6 system available.
