Killer Inn Proton Experimental

There was a new Proton Experimental update today that fixes some issues across multiple games. Killer Inn got multiple new fixes, including making sure it can actually launch on the Steam Deck, not being able to connect to Square Enix accounts, and some random hangs. There were also fixes for Monster Hunter Stories 3, Final Fantasy 7, Atelier Yumia, and HELLDIVERS 2.
