How to deal with “OSError: [Errno -9999] Unanticipated host error”? - python-3.x

Question

I am relatively new to Python. I am trying to create a program to open youtube. Here the user is supposed to say "open youtube" and python should open it in the browser. However, I am continuously getting OS error in the below code. When I tried the same program on my friend's PC, error surprisingly disappeared! But it persisted in my system for some reason. On thorough study, I found the issue is with the line "audio = r.listen(source)", where the code returns an error. Kindly help. ( I have checked my microphone, no issues seem to be there).
import pyttsx3 #pip install pyttsx3
import speech_recognition as sr #pip install speechRecognition
import webbrowser
import os
engine = pyttsx3.init('sapi5')
voices = engine.getProperty('voices')
# print(voices[1].id)
engine.setProperty('voice', voices[0].id)
def takeCommand():
#It takes microphone input from the user and returns string output
r = sr.Recognizer()
with sr.Microphone() as source:
print("Listening...")
r.pause_threshold = 0.5
audio = r.listen(source)
try:
print("Recognizing...")
query = r.recognize_google(audio, language='en-in')
print(f"User said: {query}\n")
except Exception as e:
# print(e)
print("Say that again please...")
return "None"
return query
while True:
query = takeCommand().lower()
if 'open youtube' in query:
webbrowser.open("youtube.com") #end of code
I am getting the following error message:
