Answer 1

I've found this thread because I had the same error and this is the only thing that came up.
I've resolved it by deleting the h11 and h11-0.13.0.dist-info folders in my Python environment (for you this seems like the directory is /opt/virtualenvs/python3/lib/python3.8/site-packages/) and just running pip install quart again afterwards.

Hope this helps you or someone else.
