So since halo 3 launched on steams MCC my girlfriend and I can’t play halo 3, we get like halfway through the opening cutscene before it kicks us out into separate lobbies. Even if I host it does the same thing. but it is ONLY with halo 3, we can launch and play every other available halo campaign just fine. we even tried launching without anticheat, nothing works and she is very sad now. Can ANYONE help figure out this problem please? we have already tried resetting our routers and reinstalling the game
