Looking for an old YouTube video / missing footage

Hey everyone, I’m trying to find an old version of a YouTube video that was later edited/trimmed by the channel. The weird thing is that Google still shows the old version as 49:21, and I also checked Archivarix, which has the old metadata showing 49:22 . But the current YouTube video is only around 40 minutes, so roughly 9 minutes have been removed.

I’ve tried searching Google/Yandex, Internet Archive, Archivarix, etc., but haven’t been able to find the original 49-minute copy.

any other way to recover/find the missing portion?
