If lock and unlock screen within the minute is doesn't get triggered
There's nothing in that log relevant. When you ran: kstart5 plasmashell > /dev/null did it exit? If there's a crash we need a backtrace.
Oh I see, no it didn't exit. I'll look for a crashlog then. thanks

Created attachment 158787 [details] Powerdevil Crash
The powerdevil crash looks like https://bugs.kde.org/show_bug.cgi?id=451939 That's most likely not actually related to your issue though. Based on your symptoms it looks like plasmashell is crashing. Please try to get a backtrace for that
After having initiaded a Wayland session and back to X11 now, the issue is gone. I'm sure it must have been some old config that got overwritten to a much better state and now it works as intended.
