Answer 1

Try reinstalling pip
for this download bootstrap.pypa.io/get-pip.py
and run
python get-pip.py
instruction
pip.pypa.io/en/latest/installing.html

Answer 2

Install MinGW -> this is the C compiler required for Python, if already installed then create another venv and check there, it is quite possible that some kind of conflict has occurred.
