Error code

I have the Sims 4 on PS4. I play the disc version with the dogs and cats bundle. I have also downloaded vampires and Strangerville from the PlayStation store. In addition, I have a few items from events. 
I keep getting booted from the game. It says error code (CE-34878-0). Suggested actions are to check the system software and app for updates. Both say that they are the latest versions.
