iPhone Camera app doesn't work but some other apps can still use it

I have the iPhone X with latest iOS installed. **Original Camera App:** Front Camera and Back Camera: Non of them work. Black screen. **Third Party Camera Apps**: Same issue. **SnapChat and Instagram:** Front Facing camera **works**!! but not back camera. I check the "Voice Over" feature some websites were suggesting but I don't have it enabled anyways. I have also done a “full restore factory settings” and backup/restore too. So is it still a software issue or is it time to give up on this iPhone's camera?
