Battlefront 2 crashing

I recently downloaded battlefront 2 digital on ps4 and i started playing the game and about a week after I noticed I couldn’t play certain multiplayer maps like kessel,bespin and Crait as well as not being able to play the campaign dlc resurrection I keep getting the code (CE-34888-0)  I have the game updated as in I just downloaded it and my system software is up to date as well I’m not sure what to do. Someone help please.
