I think depends when I start the shutdown. Something is wrong in shutdown routine.

Operating System

Linux

Version of Python, python-telegram-bot & dependencies

python-telegram-bot 20.5
Bot API 6.8
Python 3.11.2 (main, Mar 13 2023, 12:18:29) [GCC 12.2.0]

Relevant log output

Additional Context

Issue there is only on shutdown, is not a big problem, but is bad to see all those exceptions.
