This is probably the same thing which happened to me: When working in Jetbrains Idea, the screen went suddenly black, all applications restarted and a bunch of error reporters appeared, reporting various crashed apps.

What happens is that when the Wayland compositor (KWin) crashes then all GUI applications crash too. This is something that will get fixed eventually on a toolkit-level.
