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

Requirement already satisfied: setuptools in c:\python\lib\site-packages (49.2.1)
