Description of your issue, suggested solution and other information

I just get this error sometimes not all the time and have no idea why. As the path is not invalid. I am running on Windows 10

I got the same error, as it looks like BossDarkReaper is running youtube-dl from a c# application as myself as well.
I could avoid that error, if i changed the Attributes for the Process Method, as follows:

Code produces the error:
Process p = new Process { StartInfo = { RedirectStandardInput = true, RedirectStandardOutput = true, FileName = @"D:\Tools\youtube-dl\youtube-dl.exe", WorkingDirectory = @"D:\MyYouTube", Arguments = arguments } }; p.Start();

Code doesn't produce the error:
Process p = new Process { StartInfo = { RedirectStandardInput = false, RedirectStandardOutput = false, FileName = @"D:\Tools\youtube-dl\youtube-dl.exe", WorkingDirectory = @"D:\MyYouTube", Arguments = arguments } }; p.Start();

Hope this might help.

you can try

using double quotes for the output parameter (-o) solved the issue with video titles including the ' character.

i.e. youtube-dl.exe -i -o ""V:\downloads\audio\%(title)s.%(ext)s""

an earlier build of ffmpeg
removing the -v option
