You should remove the 4K in app name because it cannot download YT 4K video anymore! I checked many YT video that can play in 4K but your app can download only up to HD. You should fix this ASAP or don't call your app 4K.

Have you tried downloading as MKV ?
4K videos are only available in MKV format because VP9 codec is not used with mp4 files.
