Since I update Xcode (13 -> 14) and install iOs 16 on iPhone, I have this fatal error when I try to launch VNDocumentCameraViewController

I do not understand why and where the error is? before the update, the scanner worked and I haven't got this message

NSInvalidArgumentException', reason: '*** -[__NSPlaceholderArray initWithObjects:count:]: attempt to insert nil object from objects[0]'

let scannerViewController = VNDocumentCameraViewController()
scannerViewController.delegate = self
present(scannerViewController, animated: true)
code-block

I creates a new projet with only this function and It's work, there is no crash

let scannerViewController = VNDocumentCameraViewController()
scannerViewController.delegate = self
present(scannerViewController, animated: true)
