this has happened from late 1.6 beta through to 1.7.0.2. I can't log in to xbox live - as soon as it signs in the screen freezes every time the mouse is moved. this happens a few times and then it freezes completely.

sometimes I can manage to get back to desktop and close the game, other times I have to restart the pc.

turning off the windows game bar (as mentioned in another report for this problem in 1.5) does NOT work. the only way for me to play the game at all is to not sign in to xbox live
