It's crashing in FlatpakBackend::findSource(), which make sense since this is a local package without a source.

Maybe makes sense, maybe not. Can you reproduce, Nate? Can you reproduce every time, Patrick?

I cannot reproduce it by going to the Installed page like the original bug had.

yes, I can.

I am getting a crash too {not in installed packages but when i click "Application Addons" with this output

I'll insist, I am not asking for a backtrace, although very much appreciated. I am asking for the error message on the terminal output.

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
