iPhone 13 camera goes black while portrait mode

I'm using a iPhone 13 from last 3-4 months. The device is excellent but while taking shots in portrait mode it goes black & my camera app shutdown. Also, I visited a apple store for resolution but they told me that it may be some bug issue & update your iPhone. But, now, after updating. This issue is still. So, anyone has some solution or it is a common problem for all iPhone 13 users.
