Rasa Pro installation taking too long on Ubuntu

When I'm running the thread line I am running into this error:

error: No Python interpreters found in virtual environments

I'm using venv on WSL2 (Ubuntu distro).

Rasa Pro 3.8 and above is taking hours to install via pip

I have the same issue, it is taking hours and after all this time it runs into timeout error because it is not supposed to take that long. What should I do?
