I updated without thinking about it before installing a package and now plasmashell doesn’t seem to start anymore. Krunner, Meta + W, and the task switcher still work. Does anyone know of a way to fix this? Perhaps reset the desktop applet config?

There seem to be some invalid plasmoids? Or an unfinished update? The error messages like “PlasmaCore.IconItem is not a type” look like a Plasma5 version of some plasmoid as that should by now be “Kirigami.Icon” (see https://develop.kde.org/docs/plasma/widget/porting_kf6/ )
I’m not sure which plasmoid is actually giving the error message, so it might be a third-party one, that’s to blame?
