The crashing issue is something that a lot of people have issues with on console. The reason for it seems to be potentially from anything (lots of fingers pointing at bad coding). Here are a few potential solutions I've found online (from what I could gather):

• Delete install data, play for a bit, save and quit to title, reinstall data
• Someone mentioned the US patch for the game fixed crashing issues?
• Save often and pray to the gods of poor coding (not ideal)

I doubt there are a lot of people that actively check up on the forum for this game aside from myself for the past few weeks (no capture card to actually stream), so I hope late responses are okay.
