I've got a similar issue that I'm not sure I've seen posted anywhere.
My game sometimes loads up when launched with no troubles and goes right into the game.
But more often than that, I hit the play button and it opens a window like it's going into the game but it's just my desktop in an altered screen with a rainbow cursor. I "repaired" the game a few times and that worked at first but now not even that is working.
Here is the devicelog thing (I think at least lol) Thanks!
