error trying download music from youtube: ffmpeg exe exit code 1

when i tried to download music gives me this error:

What is the url of this video?

same question to download the music of film from Youtube.
Anybody knows?

What is a problem url?

It happens to almost every Youtube's url.
(I'm not allowed by system to post link for now.)
Just few cases work correctly.
I trid to use both converting methods (Standard / AntDM internal) to download music from Youtube.
It still doesn't work.

ok, post youtube video id
(https://www.youtube.com/watch?v=VIDEO_ID)

for example, the VIDEO_ID bellows:
qScw_2HDkXc

What AntDM version do you use?
I dont see any problem with Youtube audio conversion. I always use and test the latest AntDM version.

You use an external FFmpeg.exe converter. Perhaps your Anti-Virus stopped its work. Select an internal AntDM video converter - Config\Conversion\AntDM internal convestion method.

thank you for your tips!

> What AntDM version do you use?
It's the latest version (v2.3.0)

Yes I did it, too. Still can't work.
it shows "converter error FFMPEG(-22) 0xFFFFFFEA [Invalid argument]"
