Netflix causes a black, flickering screen and gets stuck. The app never launches.

Earlier today I was going to launch Netflix but nothing happend when I tried to start it, so instead I started Plex.

Ever since, when I try to start Netflix the screen goes all black, and flickers, so I can’t see anything, at all. Which I can only fix by using remote play from my computer to shut it down. Starting it again will just repeat the issue.

I’ve tried doing a hard reset, I’ve tried changing hdmi ports, I’ve tried reinstalling the app, itself but nothing seems to do it. Any ideas?

I’ve never had any issues with the PS4 or any apps other than this.
