When I use the pause menu or the encounter menu to invite friends to my team, a big version of the steam menu pops up that covers almost all of the screen but I can't actually use it or exit it conventionally. I have to use my pc's homebutton to close the game and restart it to even play the game. And whenever I move my mouse or press any keys, the character will move or the mouse will move in the game but not the pop up menu that would allow me to invite a friend.
