Error installing aiortc

[Magnarks]

Greetings, I was already working normally with Aiortc before, I think, but now I need to reinstall it to resume a project I was working on. The problem is that when I try to install it, I get the following error:

fatal error C1083: The included file cannot be opened: 'libavutil/mathematics.h': No such file or directory

I have already tried reinstalling VS Build tools, VS, Python, installed ffmpeg, but nothing solves the problem.
