Help me with Strange problem involving digital copy of CoD WW2

The game crashed and then I wasn't able to re-open it again for some reason so I deleted the game and when I went to reinstall it it said the game was still installed on my PS4. The game has crashed before but I was able to delete it and reinstall no problem. I have upgraded my HDD back in July and I am hoping my HDD isnt faulty.

I have tried rebuilding the database and unless there's any other solution that I'm not thinking of I will probably have to restore my PS4 to factory settings.

Any help would be appreciated! Thanks!!
