I’m trying to set up a custom game lobby by inviting people from Warzone Assault, but the game keeps freezing after every game and I can’t start a lobby because of this.
Power cycle a(xbox one) and reset your modem-router; if that doesn’t work, then, uninstall and reinstall the game (that worked for me).
The game commonly freezes, what some of my friends do is that they press X repeatedly and that seems to work most of the time.
