Error CE-34878-0 on PS4 may be due to your console’s system software not being up to date. You can try to solve this error with a simple software update process on PS4.
So, updating the software or, in other words, the firmware for the PS4 console is elementary if you have it connected to the Internet. Let’s assume that it is still connected, which is true in the case of most users. First you need to go to PS4 Settings. Once you’ve done that, select the section called “Updating System Software”.

After installing the update for your console, try running the game that caused the CE-34878-0 error again. If it started normally and the error is no longer visible for a long time, then congratulations, since the problem really was just the firmware version.
Solution #2 Update the game
The next possible reason for the CE-34878-0 error to appear is that a required update for the game is missing. Try to check if there is any new update for the game you are running. It happens that it could, for some reason, not be installed automatically when it exits.
