Public bug reported:
I tried to update my apps today and plasma crashed reproducibly.
I tried to started it per console and got this:

Not related to recordbox but might be related to flatpak, as I got some not
able to (un)mount some storage errors lately.
I attached some of the apps I am trying to update as スクリーンショット.
