Steam Beta fixes games from large libraries on Linux / SteamOS showing as not valid on current platform

Another day, another load of bug fixes coming from Valve for all Steam users and an especially nice one for Linux / SteamOS if you have a lot of games.

Something that does come up now and then is that the Steam client on Linux systems (like Steam Deck) can seemingly forget it's able to run Windows games via Proton. There's a few different ways it can happen, with previous bugs already solved by Valve and now they've found another related bug to squash.
