[Python] Issues Installing CVXPY with pip

I'm trying to install cvxpy using pip install but am running into an error when preparing the metadata. My current Python version is 3.13.0, and I am on Windows 11. Note that I do not have Conda.

Below is the error I encounter:

C:\Users\devap>pip install cvxpy

I tried doing pip install meson thinking that it would solve the issue with the "Project does not target a minimum version but uses feature introduced in '1.1'" error, but that didn't help. I've also installed Build Tools as per the guide here: cvxpy_guide. It seems to be erroring when trying to install SCS, but I am unsure of what to do to actually fix this issue.
