[Python] sys.prefix pointing to incorrect location, packages installing in incorrect locations

After accidentally uninstalling python earlier this day I tried to reinstall it but sys.prefix got messed up and refused to fix itself.

My sys.prefix is pointing to G:\ when it should be pointing to G:\Python.

Additionally pip is being installed in G:\Scripts and my packages in G:\Lib, when they should be installed in G:\Python\Scripts or Lib. This causes none of my installed packages to work inside scripts.

I have:

• Changed PATH, PYTHONHOME, and PYTHONPATH to the correct location.
• Created a pyvenv.cfg inside of my installation and set it correctly.
