CE-34878-0
Application Crash Error
CE-34878-0 is a general application crash code that first appeared on the PS4 and still shows up on PS5 when running PS4-compatible titles. Because it is a catch-all, it does not point to a single cause: an app bug, corrupted game data or firmware, overheating, or even unstable power can all produce it. Work through the basics in order, restart the title, install updates, update the system software, rebuild the database, and restore licenses, and keep the console well ventilated. A reinstall is the last step before contacting support.
