SUMMARY Starting Plasma 6 my favorite system monitor, so "System Load Viewer" stopped work, so I switched to systemmonitor plasmoids. Both were placed in panel. Since couple days also this stopped work. After login I can see black screen and if I would not have restore session I would thought that nothing starts. Anyway when I try to run plasmashell I can see something like this: $ plasmashell kf.config.core: Created a KConfigGroup on an inaccessible config location ":/icons/breeze/index.theme" "Icon Theme" kf.config.core: Created a KConfigGroup on an inaccessible config location ":/icons/breeze/index.theme" "Icon Theme" kf.svg: The theme "ROUNDED-COLOR" uses the legacy metadata.desktop.

Anyway this is sad that issue has not been fixed since couple days. Today happened update of packages. After that I made restart and nothing changed :(. I hope plasma will work (in Neon) soon.
Any news? plasmashell still doesn't start. plasmashell: symbol lookup error: /usr/lib/x86_64-linux-gnu/qt6/plugins/plasma/applets/org.kde.plasma.systemmonitor.so: undefined symbol: _ZN9KSysGuard20SensorFaceControllerC1ER12KConfigGroupP10QQmlEngine

I have the same issue.
Now it's fixed in KDE Neon Dev/Unstable, after the latest updates. Thanks!
