At 2022, Crypton Future Media announced a Miku Expo Rewind full of content made by fans and some clips of previous concerts. However, at some point, Crypton gave the user called BeatShobon a place (along with other people) to stream a PMV with lot of songs. It was high quality and the music and remixes were outstanding, however, after the stream, the video got deleted from Twitch, and there's no register around the internet. I even mentioned BeatShobon for the video on X back in time, and he just answered me with a smiley face(?)

The only proof of existence of this video is the screenshot I've included of a recent post by someone. Does anybody have more clues or even some kind of archive or more clips?
