PS4 game data damaged?

Since 25.01.19 my PS4 somehow has a problem. If you want to start CoD Black Ops 4, you come to the small pre-movie, and then where the brand 'Activision' is displayed, it hangs up the whole PS4 … You wait and wait until finally the screen shows that an error has happened… But there you wait a long time until you finally can do something… It is that the player file is damaged (error code CE-30005-8)

I then tried to save the game file in the online store, but where I wanted to do it was the file is broken so I could do nothing, I deleted them, did not synonymous, then I deleted the whole application and new installed… Now it works again

And at Fortnite you come to the loading screen and then suddenly comes the message 'application has been closed' or the application can't be started (error code CE-30005-8) or An error has occurred (CE-34878-0)

And for some other applications, 'an error has occurred in the application' (error code CE-34878-0), but it works when the application is restarted.

But since I have some offline games and do not want to download updates from others for hours, my question is, what can you do to make it all clear again? Or. What could have happened that many apps do not work half the time?

The error 34878 is notorious. Indicates that something is wrong with the memory data. I've had it several times in different games, but in 5 years it only happened once so far that I really had to clear the score (not game data).

I recommend that you turn off the automatic upload feature and manually back up your games regularly instead.

Oke thank you but any suggestions what I can do now, because on the Ps4 pages with respect to the error codes is one must initialize the PS4 (reset) what I do in any case auser it does not haggle over

You should:

Make backups of the memory levels of all games in which the error has not yet occurred.
switch off the automatic upload function

In the games where it already happened, and the start no longer reasonable, completely erase memory (not game data) and try again. Then all offline progress is gone, but it can't be otherwise.
