Screen Recording Blank/Black

I am on the latest release of iOS (15.5). Apple iPhone 12 Pro Max

When I use the built-in screen recorder via the control panel my screen recordings are blank. This is for all types of media/apps, e.g. games, website, the iOS platform itself.

When I finish the recording, it immediately notifies me that the screen recording has been saved to videos. I go to check it, and it's just a black screen. If I restart my phone, the screen recording function will work... a few times.. then the same issue persists.

Any ideas?
