      Note: if you need reliable uninstall behavior, then install
      with pip instead of using `setup.py install`:

        - `pip install .`       (from a git repo or downloaded source
                                 release)
        - `pip install numpy`   (last NumPy release on PyPi)

try to fall back to python 3.8,

this is not really an opencv problem, they don't maintain any pip binaries, and your main problem seems to be installing numpy

your 3.9 seems to have trouble finding a fitting numpy version, and tries to build it from scratch, from there on it all goes down ...)
