PS4 Application Corrupted (Error Code: CE-36244-9)

@Quinto21 

Try another download of the game as it may be your network settings/quality is the issue.

1. Restart the PlayStation 4 system. Then restart  the download
   
   You can restart downloads from the game's icon on the Home screen or under [Notifications] > [Downloads]. 
2. If the error occurs again, review your local network settings.
   
   - Change to a static IP or try to change the DNS server.
   - Try a different network if available.
   - The Connection may be temporarily busy, please try again later.

It is probably worthwhile using Google DNS rather than your default DNS:

This is preferable to deleting all Apex data, locally and the online storage, which as you say will lose your progress.
