Hope you are doing ok! To be fair there could be a lot of reasons behind this error. I can suggest you first update the next packages and then install numpy:

# no cache is necessary flag so it won't use the local copy of the package that could be corrupted

pip install -U setuptools --no-cache-dir
pip install -U wheel --no-cache-dir

pip install -U numpy --no-cache-dir

Also from my experience, I suggest you not use a global environment but rather use some virtual environment. It could be standard venv or poetry or conda or mamba etc, then all packages will be isolated which is good.
