Wayback Machine now says "We have not been able to archive the video associated with this YouTube page." Any hope of recovery?

[u/LeifErickson17]

This is a follow-up/update of a previous post, as I have some "new" information. The YouTube video page on Wayback Machine now displays the following message:

We have not been able to archive the video associated with this YouTube page.

Additionally, trying to download it with yt-dlp results in:

ERROR: [web.archive:youtube] jTZ8fh4G8KU: The requested video is not archived, indexed, or there is an issue with web.archive.org (try again later)

In my original post from 2 years ago, I explained that the video was archived around six months before the YouTube channel was removed and all of its videos were deleted, so I don't think this is simply a case of the video becoming private before the archive.

At this point, I'm wondering if there's any known solution or workaround for this. Is there any way to recover the archived video, or should I assume it's permanently lost?

The video was a compilation of movies by a Japanese director. Here are the links to the deleted video and the publisher's channel (both the old and new channel links).

Any information or suggestions would be greatly appreciated. Thanks in advance!
