Python windll.user32.ReleaseDC failed error

Question

I just followed some tutorial on piano tiles bot, but I've came across this error and I don't know what to do in order to solve it because Google lacks knowledge on this specific topic. I'm using Win10 x64 and Python 3.9

Here's my code:

from pyautogui import *
import pyautogui
import time
import keyboard
import win32api, win32con
import random

#X:  486 Y:  800
#X:  611 Y:  800
#X:  732 Y:  800
#X:  835 Y:  800

def click(x,y):
    pyautogui.click(x,y)

while keyboard.is_pressed('q') == False:
    if pyautogui.pixel(486, 800)[0] == 0:
        click(486, 800)
    if pyautogui.pixel(611, 800)[0] == 0:
        click(611, 800)
    if pyautogui.pixel(732, 800)[0] == 0:
        click(732, 800)
    if pyautogui.pixel(835, 800)[0] == 0:
        click(835, 800)

and here's the error that I'm getting:
