Regardless of which compatibility layer (Proton 4, 5, 7, 8, 9, 10, experimental) I use and if I use the native libraries or Steam’s, the discovery services work, but I can’t see other players in the Anomaly.
Weirdly enough, on Steam Deck it works without any issues, but obviously I want to play this on my beefy gaming PC 😥
How can I fix this?


Steam Deck runs Arch at its core. The distro has nothing to do with it.
How you have Steam installed might though. Do you have it installed via Flatpak by chance?
Installed via pacman.
Don’t defile your beautiful installation with trash like flatpak. It’s probably not the Steam installation.
isn’t steam still 32 bit…? why would flatpak be defiling, but not adding 32 bit libraries to your system?
You could try the Flatpak version, maybe. Also have you tried some DLL overrides?
