Minecraft PS4 stuck on the home screen?

My Minecraft PS4 is stuck on the start screen. I restarted the game four times, unfortunately without success.

On YouTube someone said that I should delete the game and reinstall it, but I'm afraid for my world that they will be deleted because I don't have a Minecraft account and I haven't connected my Microsoft account either.

Shall i delete it?

Actually, you could delete the game and reinstall it. I did it and the scores are displayed there again. Since you only have to delete the application, the games are not deleted either, as they are not stored on the application, but in the local memory on the ps4.

Yeah did that yesterday.
