Seen a couple of posts floating around Reddit regarding this occurrence, wanted to document mine to hopefully gain some traction. Basically I'm at final quest of the main story, Brave New World. As many are aware, quest involves springing Phineas off of Tartarus.
You can either cloak yourself as a Halcyon guard and shoot your way in, however, either method produces the same result. Soon as you come close to the door to The Pit, the game will crash.
Have also tried without companions, new saves and previous saves, to no avail. Prior to this, I have completed both DLCs. The game is on the Series X's SSD. I have referenced a link to the reddit post, with many facing the same issue. This is preventing many from completing the game. I hope a fix can come soon.
