youtube_dl.utils.RegexNotFoundError (version 2018.11.03)

[shalins]

I have the latest version of youtube-dl installed (version 2018.11.03). As of about 1 hour ago, I've been getting the following error on a majority of the videos I try downloading. It seems that Youtube just updated their api which has caused the current version of youtube-dl to break.

I tried the following command: 'youtube-dl https://www.youtube.com/watch?v=UYwF-jdcVjY --verbose'
