I ran into the same error (OSX, Version: 2.4.0). I found the fix at stackoverflow => brew install youtube-dl.

After that, the video download (output .mp4) is working, but the audio is 'missing'. Even after I removed youtube-dl and installed yt-dlp (looked at Changelog for v2.4.0).

I tried to download only the audio as .m4a and got an error, that AtomicParsley is not installed. Looked at the source code and found 4 search results with 'AtomicParsley.exe'....

The workaround for me:
Settings: Video output as .mkv
Afterwards you can use ffmpeg to convert the video as .mp4 ffmpeg -i video.mkv video.mp4

For 'big' videos this will take a while...

So another option is to download the video without audio as .mp4 and then download only the audio as .opus

Convert the .opus into .m4a ffmpeg -i audio.opus audio.m4a and add the audio to the video ffmpeg -i video.mp4 -i audio.m4a -map 0 -map 1 -c copy output.mp4

Yeah, thank you very much. I have also found the solution on GitHub(using output=.mkv) But for me, it doesn't really matter. Hopefully, somebody can actually fix the bug

Same error as reported by @Williamtung1

Currently using a newer version of ffmpeg and I have YouTube-dl already installed via Homebrew.

Cannot find a method to update the application or force it to look in the correct location for ffmpeg
