import error of comtypes in linux whil using pyttsx3 module

I am having an issue in the pyttsx3 module while using it in linux(raspberrian).When I use the module it gives an error in the following line:engine = pyttsx3.init('sapi5')

the error is:

    self._module = importlib.import_module(name)  File "/usr/lib/python3.9/importlib/__init__.py", line 127, in import_module    return _bootstrap._gcd_import(name[level:], package, level)  File "<frozen importlib._bootstrap>", line 1030, in _gcd_import  File "<frozen importlib._bootstrap>", line 1007, in _find_and_load  File "<frozen importlib._bootstrap>", line 986, in _find_and_load_unlocked  File "<frozen importlib._bootstrap>", line 680, in _load_unlocked  File "<frozen importlib._bootstrap_external>", line 790, in exec_module  File "<frozen importlib._bootstrap>", line 228, in _call_with_frames_removed  File "/home/indian53/.local/lib/python3.9/site-packages/pyttsx3/drivers/sapi5.py", line 1, in <module>    import comtypes.client  # Importing comtypes.client will make the gen subpackage  File "/home/indian53/.local/lib/python3.9/site-packages/comtypes/__init__.py", line 28, in <module>    from _ctypes import COMErrorImportError: cannot import name 'COMError' from '_ctypes' (/usr/lib/python3.9/lib-dynload/_ctypes.cpython-39-arm-linux-gnueabihf.so)

I also tried

pip install ctypes

but got the following error:

ERROR: Could not find a version that satisfies the requirement ctypesERROR: No matching distribution found for ctypes

edit-This is the code of the file I am working in

import pyttsx3import speech_recognition as srengine = pyttsx3.init('sapi5')voices = engine.getProperty('voices')engine.setProperty('voice', voices[0].id)def speak(audio):    engine.say(audio)    engine.runAndWait()def respond(q):    print(q)    speak(q)def takecommand(t):        r = sr.Recognizer()        with sr.Microphone() as source:            r.adjust_for_ambient_noise(source, duration=0.2)            print("listening...")            audio = r.listen(source)            print("recognizing...")        try:            global query            query = r.recognize_google(audio)            query = query.lower()            print(query)        except Exception as e:            if t == 1:                respond("Sorry, can you repeat that?")            takecommand(1)        return str(query)print("hello world")respond("happy life")q = takecommand(1)

I would appreciate if someone could help

Don't forget I am working on linux and this is working fine on windows
