pip: Unable to find resource `t64.exe` in `pip._vendor.distlib`

This fixed the problem for me under Windows 11, running Python 3.11.4, from PowerShell:

python -m pip uninstall pip setuptools python -m ensurepip --upgrade python.exe -m pip install --upgrade pip setuptools

@anoban To recover, you can delete the following directories:

• C:\Program Files\Python311\Lib\site-packages\pip
• C:\Program Files\Python311\Lib\site-packages\pip-(something).dist-info
• C:\Users\Anoban\AppData\Roaming\Python\Python311\site-packages\pip
• C:\Users\Anoban\AppData\Roaming\Python\Python311\site-packages\pip-(something).dist-info

And then fetch and run get-pip.py as described in https://pip.pypa.io/en/stable/installation/#get-pip-py.
