Black crow boss won't takes no damage and won't phase

I'm stuck in the first stage of the boss fight with the black crow. Got him down to 10% life and the gates won't open. He keeps chasing me around but takes no damage and I can't get out. Tried switching careacter and logging out but it sends me right back to the fight I can't get out of. Currently have xbox off and am waiting for another 20 min before I try to log on and see if it times out. Ty

Waiting 20 min worked. it timed out and I was able to leave the fight
