Looks like a bug in the library you are using. There isn't much we can do to help, you should report the issue to the maintainers of PyTube. Maybe include the full backtrace when you do.
@MarcoBonelli, Yes I did create a issue in the repo of PyTube, but no response ... that's why created a question here too ... lets see what happens

NISHANT Pacharne. I hope this problem is still relevant.

I have already downloaded several hundred videos using pytube, but today is the first time I have faced the same problem. After looking at all the complaints on the Internet, your post here and my case,I can note one common detail - all the videos that cause this problem have video_codec= avc1.64001e.

So if you write print(yt.streams.filter(resolution="1080p").first()), then you will see the fields of the <class 'pytube.streams.Stream'>, among which will be vcodec="avc1.64001e".

Note: actual name of a field is "video_codec", not "vcodec"; "vcodec" is only used for object representation.

How to fix it? I still don't know. Maybe my find will help you.
