UIImagePickerController cancel button not working when compressing video

My app provides a video upload function. But after selecting the video, UIImagePickerController will perform video compression. At this time, clicking the Cancel button will not interrupt the compression process. Is there a way to solve this problem? Reference Image: https://i.stack.imgur.com/mBSAv.png

system is iOS 12.1

 let vc = UIImagePickerController()
 vc.sourceType = .photoLibrary
 vc.mediaTypes = [kUTTypeMovie as String]
 vc.delegate = self
 navigationController?.present(vc, animated: true, completion: nil)
//when compressing video left button is not responding
