How do I solve this pygame error?

[3rr0r]

I got: “pygame.error: video system not initialized”. It was in line 29 aka the last line.

import pygame

pygame.init()

pygame.display.set_mode((1280, 960))
pygame.display.set_caption(“MultiverseTale”)

font = pygame.font.SysFont(‘Ink Free Regular’, 36)

run = True

while run == True:
    for event in pygame.event.get():
        if event.type == pygame.KEYDOWN or event.type == pygame.KEYUP:
            if event.key and pygame.K_x and event.mod and pygame.KMOD_LSHIFT:
                run = False
                pass

if run == False:
    pygame.display.quit()
    pass

def menuScreen():
    while run == True:
        pygame.Surface.fill(77, 77, 77)
        font.render(“Multiplayer”, 1(0, 0, 0))
        pass

menuScreen()
pygame.display.update
