According to here: https://support.us.playstation.com/app/answers/detail/a_id/5111/~/ps4%3A-error-codes
The steps say:
Step 1: Close the application, install the latest system software and game update, and restart the system.
Step 2: If a PS Camera is connected to the system, remove it and reboot the system, then go to [Settings] > [User] > [Login Settings] and turn "Enable Face Recognition" OFF.
Step 3: If you have upgraded the Hard Disk Drive (HDD) in your console, please re-install the original HDD.
Step 4: If the error occurs again, back up your saved data, and then go to [Settings] > [Initialization] and choose [Initialize PS4].
Step 5: If the error continues and occurs with every application, or as soon as the application starts, please contact PlayStation Support.
PS - I dont have a PS4, so I hope these make sense.
