After trying for a few days and just found out that pip and python in the project are not pointing to .venv but to anaconda due to an update. when error

no module stdnum

actually there is a problem with pip so make sure your pip path with which pip or which python

1. to solve .venv that doesn't work by deleting the .venv folder, create venv in python, and install all requirements again

rm .venv
python3 -m venv .venv
source .venv/bin/activate.fish
python3 -m pip install --upgrade pip # upgrade pip
pip install -r requirements.txt

2. since it uses vscode make sure your interpreter with ctrl + shift + P then

Python : Select Interpreter

and choose your .venv

after that you can debug as usual
