Description of the warning/error

I'm trying to generate a perpetual screen recorder that splits videos every n minutes. I got the error DEBUG:root:gdi32.GetDIBits() failed. after a couple of minutes that the script is running, like the grab command cannot take screenshots anymore.
Here is my code:

import numpy as np
import win32gui
from PIL import Image
import customtkinter as tk
import os
import logging
import sys

def get_path(filename):
    if hasattr(sys, "_MEIPASS"):
        return os.path.join(sys._MEIPASS, filename)
    else:
        return filename


def stoprec():
    global recording

    recording = False


def get_cursor():
    cursor_img = Image.open(get_path("cursor.png"))

    pixdata = cursor_img.load()

    width, height = cursor_img.size
    for y in range(height):
        for x in range(width):
            if pixdata[x, y] == (0, 0, 0, 255):
                pixdata[x, y] = (0, 0, 0, 0)

    pos_win = (0, 0)
    try:
        pos_win = win32gui.GetCursorPos()
    except Exception as ex:
        logging.debug(ex)
        print(ex)
    ratio = ctypes.windll.shcore.GetScaleFactorForDevice(0) / 100
    cursor_pos = (round(pos_win[0] * ratio), round(pos_win[1] * ratio))
    return cursor_img, cursor_pos
