Hmm, I can’t say I’ve seen that before. However, it might be worthwhile trying to just boot a live ISO of GNOME (or any other DE) just to rule out a KDE issue. Then if that doesn’t replicate the problem, try a live distro of something with a newer version of KDE (such as Fedora 39).
At the very least, that’ll help narrow down where the problem might be coming from!
