NSSpeechDriver is overriding existing Objective-C class exception with pyttsx4

[nouran-abdalazim]

I'm running the following simple code on Mac laptop M1 and python 3.8.8 using virtual environment

import pyttsx4

engine = pyttsx4.init()
engine.say('How are you today?')
engine.runAndWait()

I receive the following error " NSSpeechDriver is overriding existing Objective-C class". I can not resolve this exception

Thanks in advance

run:pip freeze and paste the output here. it maybe the objc version and pyttsx4 version conflict.
