Ps4 too slow?

My playsi has a problem.

Whenever I want to start the Ps4, it takes 15 minutes, 30 minutes or even 1 hour to start. Every now and then he shows me that the database is broken and he builds it up again. But not just once. After the database has been set up, the message appears again that the database is defective. Games such as Fortnite or GTA are laying around. Like, for example, that a tree was glitched in fortnite. If so, I can only play FIFA. This is the normal Ps4 with 500gb

where is the problem?

Sounds like she won't be doing it for long.

I don't know, delete some games and clean them.
