The file contains reference to unconnected monitor output. (Just guessing what's causing the crash)

Again the suspect I'm guessing is reference to unconnected monitor output

Sorry for not having a backtrace with debug symbols. (Don't know how to set one up) Tried this https://community.kde.org/KWin/Debugging with no useful output in the log file.

Maybe duplicate of Bug 475719 ...

Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with Plasma 6.5.0 or later? Thanks a lot!
