Going to add my name to the list of people who had trouble with the Destiny 2 Beta with this error, and had my PS4 Pro replaced via warranty service and now I am having no issues. Obviously, I can't test this against the beta anymore, but as others have noted - Rise of the Tomb Raider was another title that exhibited very very similar behavior to the Destiny 2 Beta with how it would crash. Before I sent my unit in, I tested the RotTR demo with my unit and it was crashing almost immediately after you gain control of the Lara (similar to my experience with the D2 beta). Now, with the replaced/fixed unit I can play the entire RotTR demo without any issues. (Sidenote: that game looks GORGEOUS in 4k HDR) Wish there was some other way to test that this is now fully fixed with the new unit, but I'm fairly confident that come Destiny 2 launch day I'll be OK. Reeeeeally curious how this is all going to shake out come the full launch though. Especially for those who didn't replace their units.
