Telegram not loading after upgrade to 2022.4.x: "cannot import name 'Bot' from 'telegram'"

Configuration
1

Hi all,
I did the upgrade from 2022.3.6 to 2022.4.0 (HA Core in virtualenv) and the Telegram integration doesn’t start anymore.
I read that there was a bug in 2022.4.0, fixed in 2022.4.1: I updated to 2022.4.1 and then to 2022.4.2 but the problem is always present.

These are the error messages that appear:

Invalid config
The following integrations and platforms could not be set up:
telegram_bot
Please check your config and logs.

Platform error notify.telegram - cannot import name 'Bot' from 'telegram' (/srv/homeassistant/lib/python3.9/site-packages/telegram/__init__.py)
Platform error notify.telegram - cannot import name 'Bot' from 'telegram' (/srv/homeassistant/lib/python3.9/site-packages/telegram/__init__.py)
Component error: telegram_bot - cannot import name 'Bot' from 'telegram' (/srv/homeassistant/lib/python3.9/site-packages/telegram/__init__.py)

Do you have any suggestions for restoring telegram notifications?

Here the yaml configuration:

telegram_bot:
  - platform: broadcast
    api_key: !secret telegram_api_key
    allowed_chat_ids:
      - 11xxxxxx
      - 50xxxxxx
notify:
  - name: telegram_1
    platform: telegram
    chat_id: 11xxxxxx
  - name: telegram_2
    platform: telegram
    chat_id: 50xxxxxx

Thank you

I tried to re-enable the Telegram integration now with 2022.11.3 and now is working.
So for me is magically resolved con questa operazione.
