Can you check the installed version of the `qt6-qtwayland` package, by running `dnf list --installed qt6-qtwayland` ?

If it’s 6.9.1-2, then you could try downgrading to 6.9.1-1 as per [2375356 – qt6-qtwayland 6.9.1-2 breaks KDE Plasma lockscreen, requiring user to drop to TTY to unlock session](https://bugzilla.redhat.com/show_bug.cgi?id=2375356#c4)

6.9.1-2 seems to particularly break the lockscreen, but some users have reported it causing broader problems.

**UPDATE** : a fixed version of `qt6-qtwayland`,6.9.1-3, has now been released into stable Fedora 42. So a normal `sudo dnf upgrade --refresh` should fix.
