Have PS4 repaired if the database is broken, or rather buy a new one?
New hard drive and that was it. You do not have to have them repaired so expensive.
Try to reset it with only a software error somewhere and if that does not help buy new hard drive and install yourself, you do not need to buy a new console
The yes in the workshop anyway nothing else except hard drive swap.
Accidentally pulled the plug when the PS4 was still running?
Then it may be natural that the data is not read correctly. The PS4 is not broken.
Just unplug the current operating system to a USB and install it according to this manual. Your data is gone, but the PS4 still works. In addition, many games are stored in the cloud and you can reload your scores.

or first try to rebuild the database
