        pygame.time.delay(30)

    screen.blit(BACKGROUND_FASE, (0, 0))
    pygame.display.update()
    mainClock.tick(60)

I would like to add a background image on this screen, but every time I try to make an error or it doesn't appear, how can I add a background to that part without error , the other part of the code is a menu that when I click on start this screen appears and whole code is here https://pastebin.com/Rb7jh2GH

You have to blit the background before drawing the scene, and you have to draw it in your game loop. When you draw a background, it covers everything that was previously drawn:

  1. Draw background
  2. Draw scene (all the objects)
  3. Update display

Note that there is no need to clear the background when you draw a background image. If the background image covers the entire window, there is no need to clear the background.

screen.fill(0)

while running:
    # [...]

    while 1:
        for e in pygame.event.get():
            if e.type == QUIT:
                pygame.quit()
                exit(0)

        # [...]

        # draw background
        # screen.fill(0)  <--- superfluous
        screen.blit(BACKGROUND_FASE, (0, 0))

        # draw scene (objects)
        for i in range(len(images)):
            screen.blit(images[i], img_rects[i])

        # update display
        pygame.display.flip()
