The issue is the game crashes everytime after the winner text is displayed (if either player reaches a score of 10 or greater) and fails to re-call the main() function when I stated that it should as you can see from my code below. So when it displays the winner text it should pause the game for 5 sec then break out of the while loop and recall main() but it crashes right after the winner text is displayed (see screenshot below). The logic for the winner text is near the top in my main() function.
Not sure what the root cause is since I called pygame.init() at the top of my program. Any help would be greatly appreciated! The full code is below... if someone can run it and let me know what the root cause of it crashing is that would be great. Thanks in advance!
