How can i solve "pyttsx3 errors" on macos?

Question

i am making voice assistant in python. I found example in youtube. Then i try it but when i run this code i am getting errors. Pyttsx3 can't runnning. I can't find solution. I need help. I am using MacBook M2.

Here's my code:

import pyttsx3
import pywhatkit
import datetime
import speech_recognition as sr

listener = sr.Recognizer()
engine = pyttsx3.init()

def talk(text):
    engine.say(text)

engine.runAndWait()

def input_instruction():
    global instruction
    try:
        with sr.Microphone() as origin:
            print("I'm listening...")
            speech = listener.listen(origin)
            instruction = listener.recognize_sphinx(speech)
            instruction = instruction.lower()
            if "Jarvis" in instruction:
                instruction = instruction.replace('jarvis', '')
                print(instruction)

    except:
        pass


def play_Jarvis():
    instruction = input_instruction()
    print(instruction)
    if "play" in instruction:
        song = instruction.replace('play', "")
        talk("Playing " + song)
        pywhatkit.playonyt(song)
    elif 'time' in instruction:
        time = datetime.datetime.now().strftime('%I:%M%p')
        talk('Time is' + time)
    elif 'tarih' in instruction:
        date = datetime.datetime.now().strftime('%d /%m /%Y')
        talk('Today's date' + date)
    elif 'how are you' in instruction:
        talk('Thanks boss and you?')
    elif 'what is your name' in instruction:
        talk('my name is Jarvis how can i help you')
    else:
        talk('Please repeat')

play_Jarvis()

Then i'm getting these errors:
