My Pygame Code always says "(Not responding")

I am trying to get it so every thirty seconds the square disappears and you have to find it by hovering youur mouse over it and can
move it. It is not because of my PC. Since I added:

 while not glow:
        a = 0
        b = 0
        c = 0


        if Mouse_x == x and mouse_y == y:
            pygame.time.delay(300)
            glow = True
 

my code always says not responding.

import pygame

pygame.init

spotlight = pygame.display.set_mode((700, 600))

pygame.display.set_caption("Spotlight")
Mouse_x, Mouse_y = pygame.mouse.get_pos()
x = 40
y = 40
vel = 20
a = 255
b = 255
c = 255
glow = True

run = True
while run:
    pygame.time.delay(100)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    spotlight.fill((0, 0, 0))

    while not glow:
        a = 0
        b = 0
        c = 0


        if Mouse_x == x and mouse_y == y:
            pygame.time.delay(300)
            glow = True
        
        

    

    while glow:

        a = 255
        b = 255
        c = 255

        pygame.time.delay(30000)
        glow = False
        


            


    pygame.draw.rect(spotlight, (a, b, c), (x, y, 20, 20))
    pygame.display.update()

    keys = pygame.key.get_pressed()   
        

    if keys[pygame.K_LEFT]:
        x -= vel
 
 
    if keys[pygame.K_RIGHT]:
        x+= vel
 
 
    if keys[pygame.K_UP]:
        y-= vel
 
 
    if keys[pygame.K_DOWN]:
        y+= vel
