Not downloading Youtube channel videos at all now

[speedily]

entering: command in windows "youtube-dl https://www.youtube.com/user/hiteshitube/videos" worked perfectly fine till last night but not working today. reason it says videos found in playlist is 0.

I found some apps called "Free YouTube Download" from DVDSoft that works fine in detecting total number of videos in this playlist in this case but needs at premium account to download videos.

also last night windows defender tried to block malware in youtube-dl.exe, but I bypassed it and it worked fine, tonight I didnt get any such option.

I bet there is some change in youtube.com due to which the error occured. however I think there must be an api or something to fix this.

plz help.

Same issue as you. I have a batch file that runs this command (among others):
youtube-dl -i --skip-download --simulate --verbose https://www.youtube.com/channel/UUEpT67dXwUla11Wsu4VW2DQ/videos > log.txt

Up until today I would get results like this:

Something I noticed that change on youtube is the page with the videos now automatically loads more videos as you scroll down.
