I’ve been running into a problem on this mission whenever i try to do a co-op playthrough this mission kicks me and my friend out of the game whenever we get to the cut scene. We always are trying to do a legendary run but wont get the 100% without finnishing this part.
Same thing happened to me - I tried again and when the cut scene happened I just spammed A to skip it and that work. After the final boss I also skipped the final cut scene because I was worried the glitch would happen again. Shame this hasn’t been fixed because it’s very frustrating, especially on legendary to get kicked off right at the end.
