Have you tried from command line

sudo dnf update

?

Or if you are on an Atomic system,

sudo rpm-ostree upgrade

?

3

Using regular Fedora 42 system.

My system is up to date.

Updating and loading repositories:
Repositories loaded.
Nothing to do.
4

Then no need to use Discover. Find apps via the web and download and update via console.

You could report a bug direct to KDE if you want to.

Found the solution to the problem if anyone is encountering it too.

The log mentioned “revokefs-fuse”

Doing these commands:

sudo dnf reinstall fuse

and

sudo dnf reinstall fuse3

Fixed the problem for me.
