TypeError: item 1 in _argtypes_ passes a union by value, which is unsupported.

I am getting an error for below code. Moreover, this error only happens if I use Pycharm but not in Visual Code, were sapi5 is recognized without problem, any tips? thanks

`import pyttsx3

engine = pyttsx3.init('sapi5')
voices = engine.getProperty('voices')
print(voices)
engine.setProperty('voices', voices[1].id)`

I am using python 3.8.2 in windows 10.

Similar to an error by @DebarunMitra, without issue. #6 (comment)

I fixed it temporary installing 2.7 version
pip install pyttsx3==2.7
