To add to the other answers: Yes, it is a known bug and I think it is being fixed in Plasma 6.1.2 or 6.2

PLEASE THINK CAREFULLY BEFORE POSTING HERE.
Developers do not look for reports on social media, so they will not see it and all it does is clutter up the feed.
In Fedora, I ran into the same issue, but I fixed it by running flatpak update -y in terminal. Hopefully that works on your end as well.
Unfortunately it didnt, i fixed it by uninstalling the no longer updated dependency
Could you explain how? i tried uninstalling it, but I still got the problem in discover and it will reinstall on each update somehow.
I just did flatpak remove org.gtk.Gtk3theme.Breeze
i dont know how to help you, sorry
Edit: try running flatpak install flathub org.gtk.Gtk3theme.Breeze
after running flatpak remove org.gtk.Gtk3theme.Breeze
@Blisterexe @citizenserious Because something else you have installed via flatpak has it listed as a dependency.
flatpak list --app --columns=application,runtime
This should tell you the deps I believe. I had this happen with Master PDF Reader's flatpak. It depended on very old libs. I removed the reader package which yanked the dep as well, then just installed the app another way. Not all apps are packaged by the project and sometimes are slow to update or get abandoned..
Edit replacing my original comment:
Looks like that package has been replaced by org.gtk.Gtk3theme.Breeze. That's what I'm using, and it is receiving updates.

thank you, flatpak remove org.gtk.Gtk3theme.Breeze
did the trick
Looks like a runtime is outdated and the repo to install a new runtime is missing. Then when Discover tries to update, crashes cause there is nowhere to download from
Try update the package from terminal
