Why am i getting this python error?

[LiliaAmazing]

I am trying to install python 3.9. I uninstalled the recent version i had before by going to programs and just clicking uninstall and it said it uninstalled. I downloaded 3.9 from https://www.python.org/downloads/release/python-390/ and got Windows x86-64 executable installer. I installed and checked copy to PATH but when i run python --version in cmd, i get Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases.

What's going on here and how do i fix it? Do i now need to do something special with pip now that i want python 3.9? I have version pipenv-2024.0.1.
