Comment 1 Aleix Pol 2024-09-29 16:37:46 UTC

I'll address the issue reported by this backtrace, but this won't seem to address the fact that Discover isn't working for you on SteamOS.

Comment 2 Bug Janitor Service 2024-09-29 16:52:47 UTC

A possibly relevant merge request was started @ https://invent.kde.org/plasma/discover/-/merge_requests/946

Comment 3 Harald Sitter 2024-10-01 12:43:42 UTC

What's the output of `flatpak -vvv remote-ls` ?

Thank you for all of your hard work. I reimaged the Steam deck and restored it to factory settings. Discover is fully functional now.
