--- Comment #14 from jl_kdeb...@conductive.de <jl_kdeb...@conductive.de> ---
The issue I had might be related. Backtrace attached.
App crashed on startup while loading.
App was complaining about ~/.cache/appstream/ not being writable
It was indeed owned by root. Changing that fixed discover.
The issue surfaced after completing a do-release-upgrade to kubuntu 22.10
