What could be the problem?

I had the same problem using python 3.12. I assumed newer versions would work, but the readme is correct in that you have to use python 3.10. Assuming you have python 3.10 installed somehow (sorry, I'm a linux user so not sure what you do on Windows):

python3.10 -m venv venv
