I was playing for honor and suddenly my character stopped moving and my game glitched, I thought it was no big deal but everything started going wrong. It kept asking me for an update for the system and then shut down. I restarted my PS* and took out the disc and still has the same results: I’d turn it on, it’d sound normal, before it reaches my home screen (transition where you only see the blue background) the music and screen freeze. After, my screen goes black for ** seconds to turn back on to repeat “an error has occurred in the system software (CE-*****-*). I can’t do the suggested action which is: system update, and I sent a report already. After the screen of error the whole process repeats.**How can I fix this.
