Poland

### Provide a description that is worded well enough to be understood

I am trying to download from this page (whole channel): https://web.archive.org/web/20230617094041/https://www.youtube.com/@piotr.f1267/videos

Whenever I try it just says unsupported website. For example if I try to download from this saved channel only single video it downloads without issue (even tho it's the same website): https://web.archive.org/web/20230617094121/https://www.youtube.com/watch?v=h1Iany8Etas

Is there anything to do to fix it? Why does it happen?
Thanks in advance
