I upgraded both pip and setup tools which they did but that didn't change anything

Solution

Currently, the officially supported Python versions of OpenCV are: Python 3.7 - 3.11. There's no support yet for your version (python 3.12).

You may consider downgrading to Python 3.11 and that should resolve your issue.

You can visit Pypi for more information on this.
