macOS build errors: Proxy address 127.0.0.1:7769 is not a valid URL

I’ve followed macOS instructions and when I try to build & run with ./run I get:

I’m using the latest main branch from ankitects/anki on MacBook Pro M1 from 2021. I’ve previously used Linux for building and everything worked fine. Do these error ring a bell to anyone on what might be going wrong?

So I found the problem and its solution.

As the error suggests, I had an HTTP(S) proxy setup (in my case an app called “Freedom” was automatically setting one up). After removing the proxy from “System Preferences > Networks”, the build was proceeding.
