When using IPython, window.activate() raises error.

When I am testing my code with IPython, using window.activate() raises an error.
When writing the same exact code into a .py file and running it, it works as expected.

Code:

        # activate Bloons TD 6 window.
        btd6_window = pygetwindow.getWindowsWithTitle("BloonsTD6")[0]
        btd6_window.activate()

Error:

c:\program files\python38\lib\site-packages\pygetwindow\_pygetwindow_win.py in _raiseWithLastError()
     95     information from GetLastError() and FormatMessage()."""
---> 97     raise PyGetWindowException('Error code from Windows: %s - %s' % (errorCode, _formatMessage(errorCode)))
     98
     99

PyGetWindowException: Error code from Windows: 997 - Overlapped I/O operation is in progress.

#16 is related, and the workaround used there also works here.
