And the picture use to locateCenterOnScreen() just 16.5KB.But it throw OutOfMemoryError.

while Ture:
  location=pyautogui.locateCenterOnScreen(img,confidence=0.9)
  if location is not None:
    pyautogui.click(location.x,location.y,clicks=clickTimes,interval=0.2,duration=0.2,button=lOrR)
    break
  print("Not found,retry after 0.1s")
  time.sleep(0.1)

This error will happend after 10 times or more.

I have the same problem. It happens when i use pyautogui.locateCenterOnScreen(path_img) on loop. My image has only 24.4Kb. In my case happened in iteration 1784. I would do a total of 3000 iterations.
