Big Issues after Android 13 Update

[finjaare]

I need some advice. Since I updated my Samsung Galaxy A 52 to Android 13, I have Black Bars on the side of my screen. When I'm on my homescreen, they are not there but as soon as I open an app or other things, they suddenly appear. It makes my screen way smaller than it actually is and is just annoying and strangely bugged. Please help, because I have no Idea how to fix it.

Thanks
