Hi, I just recently updated my Mac to the Big Sur operating system. Since the update, whenever I try to launch Rome II: Emperor Edition, a small box with the words "Rome II: Emperor Edition" appear and then disappear after a couple of seconds. The game is definitely running, as I can hear the background music and skip the beginning intros. However, I cannot see the game screen at all or interact with the interface with my mouse and/or keyboard. Any ideas?
