It's probably bad practice and a bit brute force, but removing ~/.cache/plasmashell/qmlcache and rebooting solved the issue. Obviously this removes personalisation settings.

I had the same issue and clearing the cache fixed it for me, thanks for the tip. FWIW I did find initially if I ran system settings from Krunner and set my Layout to Desktop and not Folderview it got me back to a more usable system, but then of course I had no Icons on the Desktop.

Thanks for saving the old bushed cache. That will help troubleshooting. Can you attach it?

Ah, can confirm removing ~/.cache/plasmashell/qmlcache remedied it for me too. I guess it was loading an old version of widgets (my plasma-nm tray icon has been having similar issues), and the lines in the error message for Folder View match changes in recent commits. > Obviously this removes personalisation settings. Which ones? I don't immediately see anything different but now I'm nervous.
Perhaps a recurrence of Bug 488326, or a related issue?
Relevant commit in plasma-desktop is: 2a89afea19309eb7fbc38000d443b7ff0e33b96b We did drop Folder.Rubberband in the plugin, but also dropped it from the QML at the same time.
(In reply to David Edmundson from comment #13) > We did drop Folder.Rubberband in the plugin, but also dropped it from the > QML at the same time. This also started happening quite a while after that commit - the RubberBand change happened in late November, the first reports of this bug that I'm aware of are from early January (after the Jan 4 changes, which included the FolderView linting and a couple of bug fixes). Though apparently (bug 514894) it may have been also broken before, but with different symptoms. All reports that I'm aware of happened with distro-packaged plasma (beta on rawhide, or master packages on openSuSE), none with self-built master.
Potentially related: some people on Manjaro seem to have problems with PlasmaExtras.Highlight not properly loading (although apparently without error messages) and not displaying highlights, which resolves itself when clearing the cache. This has apparently been happening since July 2025, but seems to be rare (two known reports, bug 515663 and https://forum.manjaro.org/t/kde-menu-entries-are-not-highlighted/180139/3).
This crash is caused by Qt, I believe they fixed some things with cache invalidation. Lets keep an eye on this and see if new issues appear.
