[2020] Blue screen (CE-34878-0) error when loading game

Hello @rico666273, have you tried to rebuild the PS4 database?

If that does not help, could you backup your current save and fully wipe the game’s data before proceeding with a clean reinstall?

Also, do you have the game installed to the console’s internal drive?
If that’s the case, would it be possible to try installing it to a different one, such as an external drive?

Thank you for the additional details, please make sure to send the crash report through the PS4 dashboard as the data received assists our developers in preventing/dealing with certain crashes.

You should be able to back up your save to an usb pen drive, as this error is usually due to data corruption. After doing so, wiping the data would confirm if the issue stems from your current data files.
