Why does the CE-34878-0 error occur in MLB The Show 21?

If you’re experiencing the error code CE-34878-0 on MLB The Show 21, it may be caused by one of the following:

Corrupted PS4 cache.

For information, let us tell you that your PS4 uses a caching system to load apps and games faster. Sometimes, the system cache can get corrupted, and this can then cause problems. If you are getting CE-34878-0 error out of the blue and the console shows other problems such as freezing and overall poor performance, then it could be due to a bad system cache.

Outdated game client or app.

Note that your game must be updated, if your game is not updated then error CE-34878-0 can also occur. The reason this is not possible for this game though, especially if you only play the online multiplayer mode is because you can't join the match without updating. Still, you might want to check if the game needs an update now to see if that will help.

PS4 software not updated.

Another important thing you need to pay attention to is to make sure that you check for the latest software updates. As with games and apps, keeping software up-to-date is one of the simplest yet effective ways to keep bugs at bay.

Random Face Recognition glitch.

If you're using the PlayStation Camera on your PS4, it's possible that the face recognition feature is behind the CE-34878-0 error. Over the years it has been noted by PS4 players that there are glitches with the face recognition feature, and some of them experienced error code CE-34878-0 because of it.

Broken PS4 database.

Certain PS4 error codes, including the error code CE-34878-0, may occur due to a corrupted database. The PS4 database may suffer from issues if game updates are interrupted during installation, or when the PS4 is turned off while system software update is underway.

Corrupted saved data.

Another possible reason that we can cite is bad saved data. If your game keeps crashing, freezing, or showing other issues aside from the error code CE-34878-0, we may be looking at a possible issue with your game data. Also, if you noticed that the crash and error only occur with one game, you can assume that it may be related to the bad state of your game data.
