Hard to say from watching a video.
It definitely popped. I was there yesterday and heard it.
Did you drill the delay grain or perhaps forget to grease the o-rings by chance? I've built a bunch of the G-79 LMS motors but haven't had any issues. I see Aerotech was posting here in this thread, they can probably tell what happened from the video and might chime in.
