pygame.error: video system not initialized when running pygame code

Question

When pressing escape to go back to main menu, the code terminated

or even whenever im trying to close the program its crashes and this is the error code:

  File "E:\pythonProject1\pong.py", line 217, in <module>
    main_menu()
  File "E:\pythonProject1\pong.py", line 42, in main_menu
    play()
  File "E:\pythonProject1\pong.py", line 161, in play
    for event in pygame.event.get():
pygame.error: video system not initialized

Process finished with exit code 1

Sorry for the long code but i dont really know what is the exact problem in my code so i sent it all:

main_menu()

the play() def is missing because i cant post it if you need it ask for it in the comments and i will reupload it.
