Pygame Passing from main to game file causing errors

Question

I receive a "pygame.error: display Surface quit" when trying to run the main.py file.

from Asteroid import Asteroid
import neat
import pygame

pygame.init()
neat.config.Config

Screenw, Screenh = 500, 500
windo = pygame.display.set_mode((Screenw, Screenh))

game = Asteroidick.Game()
game.__init__(windo)

running = True

while running:
    game.loop()
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        if event.type == pygame.KEYDOWN:
            key = pygame.key.name(event.key)
            game.input(key)
        
    pygame.quit()

Here's the Asteroid file

import pygame
import random

pygame.init()

class Game:

    red = random.randrange(256)
    green = random.randrange(256)
    blue = random.randrange(256)
    userred = 0
    usergreen = 0
    userblue = 0

    userlist = [userred, usergreen, userblue]
    points = 0 #this number increases every time you input the right color value.
    teext = f"Points: {points}" # + points
    i = 0


    def __init__(self, screen):
        pygame.display.set_caption("Asteroiiid")
        self.screen = screen
        self.screen.fill((255, 255, 255))

    def checker(self):
        righty = True
        if(self.userlist[0] != self.red):
            righty = False
        else: 
            self.points += 1
        if(self.userlist[1] != self.green):
            righty = False
        else: 
            self.points += 1
        if(self.userlist[2] != self.blue):
            righty = False
        else: 
            self.points += 1
        if righty:
            self.points += 1
        self.red = random.randrange(256)
        self.green = random.randrange(256)
        self.blue = random.randrange(256)
        self.userlist[0] = 0
        self.userlist[1] = 0
        self.userlist[2] = 0 
        self.i = 0

    def loop(self):
        self.teext = f"Points: {self.points}"
        if self.i == 3:
            self.checker()      
#<----------ERROR OCCURS HERE----------------->  
        self.screen.fill((self.red, self.green, self.blue))
        font = pygame.font.SysFont("Arial", 24)
        score = font.render(self.teext, True, (0,0,0))
        redval = font.render(str(self.userlist[0]), True, (255,0,0))
        greenval = font.render(str(self.userlist[1]), True, (0, 255, 0))
        blueval = font.render(str(self.userlist[2]), True, (0,0,255))

        self.screen.blit(score,(0,0))
        self.screen.blit(redval,(400,100))
        self.screen.blit(greenval,(400,200))
        self.screen.blit(blueval,(400,300))
        pygame.display.flip()

    def input(self, key):
        if (key == 'up'):
            self.userlist[self.i] += 1
        if (key == 'return'):
            self.i = self.i + 1
        else:
            self.loop()
        #I think I'll just have the user enter values

pygame.quit()

If I comment out self.screen.fill((self.red,self.green,self.blue)) line, I receive a different error on the fonts.

I have been slowly building this file up and I've just moved the window to main. It worked before when I did not pass window to Asteroid. The init method also doesn't get errors, either.

When pygame.quit() is executed, all installed PyGame modules are deinstalled. All modules that were installed with the corresponding init call (or pygame.init()) are deinstalled. Every following call to a PyGame API function will cause an error. You must not call pygame.quit() in the application loop. Call it after the application loop.

while running:
    game.loop()
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        if event.type == pygame.KEYDOWN:
            key = pygame.key.name(event.key)
            game.input(key)

#<--|        
pygame.quit()
