XenaRose92, I'm Sorry to hear that you have been crashing. This being technically an offline game, there are no servers. It's a single-player run-through game, so the only time it needs to connect online is to update the game if there is a patch.
Does this happen when another PlayStation user creates a character?
Have you started a playthrough not connected to the internet?
Are you playing the game on an internal or external drive?
Do you have enough free storage space on your PS5?
Are you using a physical copy or a digital version of the game?
Can you list the steps you have tried to resolve this on your end?
Thanks!
