[iPadOS18 Beta3] on iPad 7th gen, camera app cannot detect QR code

Hi,

After installing iPadOS18 Beta3 on my iPad 7th gen, the default camera app no ​​longer detects QR codes. I tried updating to Beta7, but the issue remained.

Also, third-party apps that use AVCaptureMetadataOutput in AVFoundation Framework to detect QR codes also no longer work.

You can reproduce the issue by running default camera app or the AVFoundation sample code from the Apple developer site on iPad 7th gen (iPadOS18Beta installed). https://developer.apple.com/documentation/avfoundation/capture_setup/avcambarcode_detecting_barcodes_and_faces

Has anyone else experienced this issue?

I would like to know if this issue occurs on other iPad models as well.

This is similar to the following issue that previously occurred with iPadOS 17.4.
