That’s very strange, haven’t encountered that. And when you restarted the game, the same thing happened? Can you confirm that you exported and installed all the games files to your programs 86 directory, and not the normal programs directory?
im sorry you’re having trouble with it! My only other recommendation would be, try installing it to the normal programs (not programs 86) directory and see if that fares better. Does the game load at all? Usually it takes a few to boot after running the program
