  • I just bought Rust app id# unknown. I just got a Steam Deck so to cellabtate I bought the game I wanted for a while. "Network Error can not find anti cheat software" is all i will say while trying to start the game. Totally reproduceable. I will be looking for a refund.

Hello @MrTKusa, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/3104#issuecomment-4436526026.
