Hi, I am a KDE Neon user too. While I never had this specific problem, I had various severe bugs appear randomly after system updates. Usually they get fixed again in future updates. So check regularly for system updates to see if this gets fixed.
Additionally try switching global theme for example from Breeze Dark to Breeze Light. Sometimes the global theme gets corrupted.
That is how it sort of works the steam store displays the games the games that work with the deck. You can install other games but you get the a warning that either it has not been testet enough to make sure that it works, or that it is not recommend because that issues with the deck.
Kde neon is the best thing to do with the dentist and the other one is the one that is good.

This is also my experience. The results are usually very vaguely related with what I search. I had better luck with Wikipedia comparison tables, but often they are incomplete.
I agree but that is a different problem
Do you use VPN? I get that error since I started using vpn and I need to switch remote connection.
