First it was EA breaking everything on Linux and Steam Deck and now it's Ubisoft telling everyone to hold their beer. Third-party launchers on Steam are once again being a massive nuisance. Update 22:11: Valve released a Proton Experimental (no Beta needed) fix for this.

If you go into the Properties on Proton Experimental in your Steam Library, and opt into the "bleeding-edge" Beta, then set your Ubisoft games to use Proton Experimental it will fix it for now until a proper Proton update is out. Note: using it can cause other issues, the Beta doesn't have a lot of testing, you've been warned. It also bears mentioning that games bought from third party stores can be integrated into Steam with community-made tools, and when they are launched this way, they are less intrusive than games bought on Steam that are bringing their own launcher.Update 21:17: Looks like Proton developers have updated the "bleeding-edge" Beta for Proton Experimental, that works around the issue. I'm sure that these companies would respond by absolutely crippling the functionality of their game when launched this way, but I think that it needs to be possible. What I think should be mandatory is not a complete abolition of third-party launchers from the Steam store, but the ability to go straight into the game without any middlemen. Cross-play is not a valid defense for third-party launchers shoving themselves in the middle, because a wide variety of games implement it just fine without a whole-ass program between the storefront and the game.Their stupid launcher did, because it is probably trying to do a bunch of things that nobody wants. It broke games that were already working, because it's an additional point of failure.Steam Deck is aiming to create a console-like experience, and consoles absolutely do not allow games to shove launchers in the middle.It mainly only serves to tell the player, "hey, you could have bought this from our store! you should have bought this from our store! we exist, and we want to make sure you know that! give us more of your money and data!" It's not that the third-party game store exists, it's that it has shoved itself between the store the game was actually bought from and the game itself, which only negatively impacts the experience.

Your non-productive and blatantly provocative reply ignores several facts.
