What Happened: I right clicked on my dock panel on the bottom of my screen and clicked "Show Panel Configuration" as i wanted to adjust a setting. the desktop immedietely froze and became unresponsive. I could still use Krunner, so i invoked it using ALT+SPACE and used systemctl --user restart plasma-plasmashell.service to restart plasma. as KDE seemed to not be able to recover from the crash on it's own. It has not reoccured and that is unfortunately all of the information that I presently have. I do not know if the bug is reproducible, nor the nature of the crash (if it''s software, hardware or firmware causing the problem.

I apologize if my bug report is under-utilized, this is my first bug report and i am not fully versed on how to provide the most detailed information for a bug report, as I am a end user

The crash can be reproduced sometimes.
