Photos come out over exposed when using Portrait Mode

When taking pictures in Portrait Mode, I'm starting to get extremely over-exposed photos automatically produced. These were taken on Iphone 13 Pro Max with iOS 16.5. In live view on the camera app, they appear correct, but get a completely different result once the photo is taken. I have not adjusted any of the exposure settings or post processing settings myself, just clicked on the subject to get focus and took the picture.

Is anyone else experiencing this issue of having photos over-exposed when using Portrait Mode? Any suggestions on a fix would be appreciated. I've tried rebooting the apps and phone, and do not believe a re-installation of iOS will make a difference.
