Game loads fine and plays normally 1st run. Trying to log in a 2nd time the game screen starts and goes black then white and stays white, loading does not continue. I have tested this on 2 new M1 Macintosh machines, same for both of them.
I have submitted to support 2 times, 2nd is support #4259618.
They suggested basic stuff, did these and still the same.
The Apple OS has a user called “Guest User” which is designed to be a guest user. When the guest user logs out all the local files are dumped and the next login is a new setup. I have been able to run the game while in the “Guest User” and it will not launch the game a second time, but first run works fine. If I log out the guest user account and then log back in as the guest user the game will again run properly as a “first run” so I can play the game in this first run scenario. If I have to quit the game for some reason the game will not relaunch until I log out of this guest user and log back in as guest user. This indicates to me that the game is creating some file the first time it runs which will not allow the game to launch properly again.
