The Real Player Down Loader has the latest update. I am able to download some old You Tube videos. However, I am unable to download the newer You Tube videos.

Yesterday, the app tried to download a few videos and stopped about ten seconds into the download. I got the message: Unable to download the video.

I tried to update Real Player, and I got the message "You have the latest version"

The app works on other websites. 

Windows 11, Microsoft Edge

Please advise. Thanks.
