Ask him where he is playing? Mybe he plays on a steam deck or on Linux. Because ppl suggested them to use the beta feature. That means that they have a different version of the game. What is automaticly disabled the multiplayer option between the current version.
This is why I think this is not a solution for steam deck and Linux users.
Great example if someone with Linux or SteamDeck want to play with a user hou plays on cloud Gaming.
Its not possible at all at this state of the game.
