Black thing at the top of my screen.

A few days ago this little black area popped up on my home screen at the top. I have an iPhone 12 so it isn’t the Dynamic Island, doesn’t appear when I’m in any other apps. Any help on what it is or how to get rid of it? I’ve tried google but I can’t find anything other than the Dynamic Island but I know it isn’t that.
