After an initial period of not running on the Deck, the Proton Hotfix branch allowed the game to be playable - we even had an influx of people showing their macros and settings for the Deck.
However, today, mine is only showing a black screen. GE-Proton, Proton 9, Proton Hotfix - it doesn't matter, just a black screen. If I spam "A" I sometimes get an anti-cheat error.
Anybody else having issues? It's not the servers being down, as I can play normally on my PC.
