崩溃(iOs16)出现时VNDocumentCameraViewController

Question

对于iOS 16，当我在我的项目上启动VNDocumentCameraViewController (iPad或iPhone)时会出现致命的错误，而对于旧的操作系统(如iOS 14、iOS 15)，我没有这个错误。info.plist --> NSCameraUsageDescription提供了描述

let myScanViewController = VNDocumentCameraViewController()
myScanViewController.delegate = self
self.present(myScanViewController, animated: false)

我碰巧在self.present之后，我没有相机屏幕。我不知道在哪里检查和添加断点。

调试消息:由于未登录的异常“NSInvalidArgumentException”终止应用程序，原因：__NSPlaceholderArray initWithObjects:count:：尝试从对象中插入零对象

我检查了回溯，但对问题有任何想法。谢谢你的帮助。

解构后，所有的projet....the包SumUp (通过pod安装)都会导致crash....the回溯，这确实是不明确的致命错误！
