Borderlands 2 freezes/ crashes at every check/save point ps4

I’ve been playing bl2 off and on since it first came out on ps3. Now I can’t play at all it crashes every time somebody hits a checkpoint or when the game saves. it does this worse online but also does it in single player mode. I have deleted and reinstalled the game a couple of times and even deleted my profile data. I really like the game it’s kinda my go to time killer. Anyone have any ideas?
