No module named 'Librosa'

[TraumaBeast]

I have spent hours trying to get this set up and it refuses to work.
I installed Python 3.9, I have every other dependency installed.
I ran through the setup carefully and made sure everything installed.
I have librosa, it shows up in python, but unlike any other module, it refuses to load.
It just points to the line for import librosa in main.py

I read online librosa only supports up to python 3.7, I tried using that, same result.
Installed 3.9, reinstalled all dependencies, same result.
I moved the installed files, same result.
I upgraded pip and reinstalled dependencies again, same result.
I changed environment paths, same result.

I have AICoverGen and RVC on a non-OS drive, but RVC works fine, it's just librosa here not being found for some reason.
Any ideas? I'm not exactly super well-versed with python, so it's liable to be a fault of mine.
