AttributeError: 'zoneinfo.ZoneInfo' object has no attribute 'zone'

I am facing this error when I try to use calendar.

import datetime as dt
from O365 import Account, FileSystemTokenBackend
import os
import re

CLIENT_SECRET = 'xxxxxxx'
CLIENT_ID = 'xxxxxxxxxx'
TENANT_ID = 'xxxxxxxxxxxxxxx'
EMAIL_ID = 'xxxxxxxxxxxxxxx'

def calendar_event():
    credentials = (CLIENT_ID, CLIENT_SECRET)
    token_backend = FileSystemTokenBackend(token_path=os.getcwd(), token_filename='my_token.txt')
    account = Account(credentials, tenant_id=TENANT_ID, auth_flow_type='credentials', token_backend=token_backend)

    # Checking whether the client is authenticated.
    if not account.is_authenticated:
        try:
            account.authenticate()
            print('Authenticated!\n')
        except Exception as e:
            print("Exception: ", e)
            print("Authentication Failed!\n")
    else:
        print('Already Authenticated!\n')

    schedule = account.schedule(resource=EMAIL_ID)
    # print(schedule)

    calendar = schedule.get_default_calendar()
    print(calendar)

    new_event = calendar.new_event()  # creates a new unsaved event
    # print(new_event)
    new_event.subject = 'Recruit George Best!'
    new_event.location = 'England'

    # naive datetimes will automatically be converted to timezone aware datetime
    #  objects using the local timezone detected or the protocol provided timezone

    # new_event.start = datetime.now()
    new_event.start = dt.datetime(2021, 9, 7, 11, 45)

    # new_event.recurrence.set_daily(1, end=dt.datetime(2019, 9, 10))
    # new_event.remind_before_minutes = 45
    new_event.save()


if __name__ == '__main__':
    calendar_event()
