"Parameter is incorrect" `COMError` with `ControlFromCursor` function

This error happens when you retrieve elements with ControlFromPoint:

    control = auto.ControlFromCursor()
  File "Z:\Repos\rpaframework\packages\windows\.venv\lib\site-packages\uiautomation\uiautomation.py", line 8190, in ControlFromCursor
    return ControlFromPoint(x, y)
  File "Z:\Repos\rpaframework\packages\windows\.venv\lib\site-packages\uiautomation\uiautomation.py", line 8168, in ControlFromPoint
    element = _AutomationClient.instance().IUIAutomation.ElementFromPoint(ctypes.wintypes.POINT(x, y))
_ctypes.COMError: (-2147024809, 'The parameter is incorrect.', (None, None, None, 0, None))

in the following scenarios (where by point I mean retrieving the element at cursor's position):

  1. Point Calculator display, then its title bar.
  2. Point in Chrome and then its address bar or Desktop.
  3. Point inside the latest Notepad and then point to its title bar.

Sorry, I don't have an ARM Windows, I can't reproduce the issue.
