Solução
A primeira coisa que fiz foi limpar a pasta C:\Users\Administrador\AppData\Local\Temp
Observe que no meu caso estava com o usuário Administrador, e na sequência fiz update/install com os comandos a seguir:
> pip install pip --upgrade
Requirement already satisfied: pip in c:\python\lib\site-packages (21.1.1)
> pip install setuptools --upgrade
Espero que ajude, e se lhe ajudou comente!!!
