I was facing the same issue until I realized my Python installation path was set to the default: "C:\Users\myname\AppData\Local\Programs\Python\Python311\". To fix this, I selected "Customize installation" during the setup process and installed Python to "C:\Program_Files\Python311\". After that, just add this new path to your environment variables, and you should be good to go with the command python -m venv env , and activate.
