System Settings app not appearing in search

After upgrading to KDE 6.6 on KDE Neon, the System Settings app no longer appears in the search box (either the Alt-Space search box or the Meta launcher)

The app still exists and can be run from the console or a dedicated quicklaunch shortcut, and individual preference panes show up in the search, but not the overall System Settings app.

I tried running kbuildsycoca6, balooctl6 check, apt install --reinstall systemsettings, and restarting my session but the app is still missing from search.

Found the issue – I had previously made a custom quicklaunch shortcut to open the Display Settings pane (by creating a launcher and adding the argument kcm_kscreen to it). This created a file ~/.local/share/applications/systemsettings.desktop. This was obscuring the original file usr/share/applications/systemsettings.desktop. After changing the name of the custom shortcut file, I can see the regular System Settings app in search again.
