Symptoms

Starting causes:

Network Error:
No anticheat module has been found for this game and platform

(Facepunch or Valve has fixed this error before it worked like 10 months or 4 months ago, but with the release of the Steam Machine it would be nice if this could be fixed in any way)

Reproduction

Just Start Rust with probably any Proton version.
