When you try to go in and out of fullscreen, ALL of the menu buttons become unclickable. Even the one that says "back to game". Note that pressing Esc does work and can bring you back to the game which is NOT frozen. Freezing all of the video game setting buttons results in the fullcreen button saying "off" when it IS in fullcreen.
I think that "duplicate" is a different bug because when my game freezes, you can't interact with the buttons. You can only press esc to play the game as normal. You can play the game but not go to the menu screen. Also, my bug is in a different version. AND, I'm trying to switch between fullscreen and smaller screen, not minizing and maximizing.
