I don’t know, but I’d ensure the app isn’t running (I’d assume you’ll know that, but you could always use killall plasma-discover anyway) and then start it from terminal.

The reason I’d start it from terminal is any messages appear on the terminal, instead of me needing to go looking in machine logs…

eg.

guiverc@d7050-next:~$   plasma-discover
libs QList("/usr/lib/x86_64-linux-gnu/qt6/plugins", "/usr/bin")
org.kde.plasma.libdiscover: OdrsReviewsBackend: Fetch ratings: true

AppStreamIntegration: No distro component found for "com.ubuntu.ubuntu"
Terminated

Whilst I’m not running 24.04, I provided the start of what I see… then I stopped pasting, but included the final termination being when I ran ‘killall plasma-discover’ in another terminal.

I’d hope some clues as to problems may appear in your listing; this being an easy first step anyway.
