Egg Generator menu bug

[Former user]

HI! I only found out today about the "Egg Generator" menu in the main menu and after looking at it, tried to exit without actually making one. It seems to be stuck on the screen now with it just flashing repeatedly to a plain black screen (or at least a darker version of the screen). I can't quit out of the program at all, even using the X at the top right and clicking "close program" on the taskbar.
