On the final hit of the boss I was dead and was respawned at the beginning of the dungeon, my teammate who killed the boss, was then also ported to the beginning and the whole fight was reset. After beating the first phase again, the game froze, black screened, and then kicked us out stating destiny 2 server error connection. We didn't get credit for anything and received no loot or save point. Please help:(( PS5 and Xbox 1 cross play both players had the same issue at the same time. Occurred 10:15 am PST 11/13/2023.
