Description

It's been a week since I downloaded the library\ program... Neither one nor the other works AT ALL, no matter how I shove the link and, no matter what, it goes to this or similar error. Even if I insert links that worked before, errors still remain

[igorir3]

Okay... I found the answer in, which told me to switch to yt_dlp... We need to look for information better...
