For those having problems with youtube-dl, there's already a script to use yt-dlp here:

https://gist.github.com/jonath92/039e998b3d3f6ba4afd5d5c671eaedf1

Then right click Radio++ icon > Configure, go to Preferences tab and choose yt-dlp as the CLI tool.

Make sure the Download directory exists, I had to create the folder Radio or else it would fail.
