ytdl-core stopped downloading youtube videos - I get invalid or unexpected token

I used ytdl-core for downloading youtube videos but now it stopped working after 2 months when I run my app

SyntaxError: Invalid or unexpected token

Solution

Here you can find some workarounds, putting the library back into normal operation
