In my Fedora 37 system, since a recent update with more than 350 packages the PackageKit (“Software Updates”) applet in the system tray doesn’t load anymore.

STEPS TO REPRODUCE
1.  Start KDE session in Fedora 37
2. Click the Software Updates icon in the system tray and observe the error message.

OBSERVED RESULT
Message of Software Updates (Get software updates) icon:
Sorry! There was an error loading Software Updates.

file:///usr/share/plasma/plasmoids/org.kde.plasma.pkupdates/contents/ui/main.qml:25:1: plugin cannot be loaded for module “org.kde.plasma.PackageKit”: Cannot load library /usr/lib64/qt5/qml/org/kde/plasma/PackageKit/libplasmapk_qmlplugins.so: (/usr/lib64/qt5/qml/org/kde/plasma/PackageKit/libplasmapk_qmlplugins.so: undefined symbol: _ZN5Solid3Job16staticMetaObjectE)


EXPECTED RESULT
- The loaded applet, updates info.
