Created attachment 162484 [details] complete journalctl SUMMARY *** Hello, I can't start KDE Neon because plasmashell seems to crash after the login. It worked until I've done the last updates with pkcon update few hours ago. I saved the journalctl log and found some "defined Version=5 but Version=6 was expected" errors but I don't know how to read the it correctly so I attach it. Other errrors which may be useful: kded6[1564]: QDBusAbstractAdaptor: Cannot relay signal KDBusObjectManagerServer::InterfacesAdded(QDBusObjectPath,KDBusObjectManagerInterfacePropertiesMap): Unregistered input type in parameter list: KDBusObjectManagerInterfacePropertiesMap plasmashell[1277]: /usr/bin/plasmashell: symbol lookup error: /lib/x86_64-linux-gnu/libKF6KIOFileWidgets.so.6: undefined symbol: _ZN16KBookmarkManager14managerForFileERK7QString and many others. I can only CTRL+ALT+F3 to a new shell. Let me know how can I provide more useful information if needed *** STEPS TO REPRODUCE 1. Boot the system 2. login on SSDM, which works fine OBSERVED RESULT Just after the login plasmashell seems to crash and I only see the cursor on a black screen EXPECTED RESULT Should work :) SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: 6 KDE Frameworks Version: Qt Version: 6
Sorry for the double post, but I also tried on X11. Same behaviour on X11 and Wayland session. After the login, I can see the desktop for a moment (just a blink, less than 1 second) then I see the black screen with the mouse cursor only

After the last updates (using "dist-upgrade" because "pkcon update" didn't find any update) the problem is fixed. Thanks.
