Why does the camera screen automatically rotate 90 degrees when entering the page on iOS devices?

At this point, I exit the page and turn on the Camera app of the system. The direction is normal, and then switch back to the meeting page,The camera direction will return to correct, but after entering the room, the camera direction is incorrect again.
Anyone encountered this problem?
