I receive this error after the lookup and selecting the file icon. I have attached a file of the command line output. What am I doing wrong?

Thanks for your help.

This is an unusual error, and it looks like it has to do with youtube-dl. Try updating youtube-dl and re-downloading the FFmpeg binaries, and see if you still get the error.

This issue is still present. I updated youtube-dl and FFmpeg and still, the error is present.

What OS are you using? Do you always get this error, or only with certain settings (custom tags, custom path, etc.)?

Thank you for the detailed breakdown! I'm thinking that something is going wrong in application.py, but there are a few try-catch statements after line 58 so it's difficult to pinpoint where the error is occurring. Try replacing application.py with the copy I've attached (rename the extension to .py, GitHub doesn't allow attaching .py files directly) and you should get a more detailed error report.

Looks like youtube-dl expects sys.stderr.buffer to be a BufferedWriter object, but for some reason, your console returns a string object. Where are you running the program from (cmd, PowerShell, etc.)?

Also, what is returned when you run the following code?

import sys
print(sys.stderr.buffer)

You have to run the code in the Python shell. In cmd, first type in py, then press enter. You should see a message telling you your Python version and some other info (make sure this is Python 3+, if it's not, then try running python instead). Type in the first line (import sys) and press enter, and then type in sys.stderr.buffer and press enter.

If that doesn't work, then save the two lines of code as a .py file and run it as you would run any Python file.

I'm not exactly sure what is causing this problem; I suggest you open an issue over on youtube-dl and see if they can help. In the meantime, does using PowerShell or another terminal prevent the error?
