ModuleNotFoundError: No module named 'async_timeout'

Additional Information

To overcome the problem, a simple
pip3 install async_timeout fixes the issue

It seems this only happens for Python < 3.11.3. So a possible fix is to set the min required python version to 3.11.3 or add the package in the pyproject.toml>= 3.11
