First of all make a good title, or else no one that knows how to fix your issue will click on it. I am not familiar with the PS4 but try clearing your cache.
1. Turn off your PlayStation 4. Do not enter Rest Mode. 2. Once the indicator light on top of your PlayStation 4 is off and has stopped blinking, unplug the power cord from the back of your console. 3. Wait at least 30 seconds. 4. Plug the power cord back into your PlayStation 4 and turn it on.
