I am unable to find workaround for this

Could someone please help

my python version is 3.10

[Karthikdasari0423]

Here is workaround,

Downgrade to python 3.9 worked fine

root@ubuntu:~# python3 -V
Python 3.10.6

cd /root/
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
sudo apt install python3.9
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.10 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.9 2
sudo update-alternatives --config python3

root@ubuntu:~/aioquic# python3 -V
Python 3.9.16

sudo apt-get install python3.9-distutils

pip3 install wsproto
pip3 install Jinja2==3.0.3
pip3 install werkzeug==2.0.
pip3 install asgiref
pip3 install starlette
pip3 install httpbin
pip3 install httpx
pip3 install aioquic
pip3 install 'flask<2.2.0'
pip3 install werkzeug==2.0.

cd /root/aioquic/
python3 examples/http3_server.py --certificate tests/ssl_cert.pem --private-key tests/ssl_key.pem -v

if any issues with pip or apt:-
cd /usr/lib/python3/dist-packages
sudo ln -s apt_inst.* apt_inst.so
sudo ln -s apt_pkg.* apt_pkg.so

This look it should be reported in a different project..
