ModuleNotFound Cython error in Conda

edit

I followed the exact instructions found here: https://doc.sagemath.org/html/en/inst...

It seems to install fine but as soon as I launch it, I get the errors below;

I tried pip install cython but it's already installer

Ubuntu 22 python 3.7 and 3.9 tried both with the same result. I have no idea how to fix this or if it's fixable. Sage 10, but using python 3.7.installs sage 9.6 with the same problem.
