I reset the Plasmashell settings by deleting  ~/.config/plasma-org.kde.plasma.desktop-appletsrc and ~/.config/plasmashellrc. The bug is gone.

Comment 3 Nate Graham 2024-12-11 22:39:55 UTC

Cool. However unfortunately that means we can't debug or fix this, because the backtrace doesn't make much sense, and the configuration used to reproduce it is gone now. :/ Oh well, maybe another time.
