title: pygame.error library not initialized And pygame.error video sistem not initialized when I use pygame.init and pygame.font.init
body: <p>I am making simple game about clicking circles to learn pygame. I initialize pygame and pygame.font but it gives me an error randomly when I play the game. When I close the game before I get that error it gives me a diffrent error (pygame.error: video system not initialized)</p>
