If you receive Error Code CE-34878-0 while playing Dead by Daylight on PlayStation 4, we recommend trying the following troubleshooting steps:
- Close Dead by Daylight.
- Ensure that both your system software as well as Dead by Daylight are updated to the latest versions. If not, make the necessary updates and then restart your PlayStation 4.
- If the error persists, please back up your saved data and try the following:
- If you have upgraded the Hard Disk Drive ("HDD") in your system, please re-install the original HDD.
- Go to "Settings" > "Initialization" and choose "Initialize PS4".
This should hopefully resolve the issue, however, if it persists we ask that you please reach out to PlayStation Support here.
