Are you in the Beta testing programme @Fatal1tyv2 to be using Samsung One Ui 3.0 ?
Beta can and will break features as it goes through the different Beta versions.

Samsung One Ui 3.1/ Android 11.
I have the EXACT same issue. Received the Android 11 / 3.0 UI upgrade on Thursday. Staring at the now-reappeared front camera cutout on my Samsung Galaxy s20 Ultra. Infuriating as the full screen apps option to hide it, IS in fact gone!
Ooo not that I've noticed. Save for additional / quicker battery drain seeming a bit quicker than normal. That and the Sound Assistant is confusing. But that is possibly "user error."
