iPadOS 17.4.1: AVCaptureMetadataOutput delegate not called

After my iPad 6 upgrades from iOS 17.3 to 17.4, the AVCaptureMetadataOutput delegate is not called anymore. I find there is the same problem in a stackoverflow post:

https://stackoverflow.com/questions/78128010/ipados-17-4-avcapturemetadataoutput-delegate-not-called-qrscanner

An Apple webpage said the "QR code scanning" issue is fixed in iPadOS 17.4.1:

If your iPad is unable to scan QR codes after updating to iPadOS 17.4 - Apple Support - https://support.apple.com/en-lamr/118614

That's true, I confirm that on my iPad 6.

But, unfortunately, iPadOS 17.4.1 does fix ONLY QR code scanning! It doesn't fix barcode scanning, like PDF 417
