Unable to Run in Non-Administrator Mode After Windows 10 Update

[seaspeak]

After installing Servicing Stack 10.0.19041.5676 during a recent Windows 10 update, the application pyttsx3 can no longer be executed when using non-administrator mode. This issue was not present prior to the update. The application works without issues in administrator mode, but non-administrator mode now fails consistently.

  File "C:\Program Files\Python37\lib\site-packages\pyttsx3\__init__.py", line 20, in init
    eng = _activeEngines[driverName]
  File "C:\Program Files\Python37\lib\weakref.py", line 137, in __getitem__
    o = self.data[key]()
KeyError: None```
