python2 crashes division by zero

[ersteller]

time_rate = (clock.get_time() / 1000.0) / (1 / max_fps)
ZeroDivisionError: float division by zero

I know python 3 would convert the right term to float but
python 3.9 (on win10) is not loading numpy correctly:
RuntimeError: The current Numpy installation ... fails to pass a sanity check due to a bug in the windows runtime. See this issue for more information: https://tinyurl.com/y3dm3h86

You should try to update windows.
