Same issue here. I have a GOG version of the game. Split-screen is activated everytime I turn on my XBOX controller. I deactivate it by long-pressing the left stick, but when I open the Multiplayer menu, a message pops up saying that a new player is now connected. I go back to the Main menu, log off the second player again, return to the Multiplayer menu to get... the same message about a new player connection. Tried to select a controller as a main input device in Settings menu, but it helped just once - I was able to join a party as one player. After I restarted the game the next day, I got the same issue and I couldn't de-activate split-screen even after I turned off my keyboard from the Settings menu. I even tried to unplug my keyboard and start the game with the controller only - no result. Moreover, when I continued the game session with a keyboard as an input device, I was unable to open any of the 3 chests (there's 3 of us playing) in the camp.
That's really frustrating! frown
