Getting QML errors for these settings panes: Shortcuts, Audio, Display and Monitor, Bluetooth, Thunderbolt, Firewall, Wallpaper, all Colors and Themes pages, Fonts, Notifications, Desktop Effects, Window Rules, KWin Scripts, Virtual Desktop, General Behaviour, all Search, Legacy X11 Applications, User Feedback, Region and Language, Power Management, Automatic Launch, Session pages KDE neon Unstable, latest master. Plasma 6.1 dev. I might have missed some, maybe some sort of test to check these would be nice?
Please ensure all your packages are up to date. It'll be a downstream issue
This usually goes away when I clear the relevant QML cache suggesting there’s an issue with Qt’s qml module qmlcachegen situation.
Try removing ~/.config/systemsettings and see if the problem goes away.
~/.cache, not ~/.config
