Privacy keys added but still crash on dismiss UIImagePickerController - swift

Question

Going Crazy。
Using UIImagePickerController to take picture,
After presenting the pickerController, cosole prints
[MC] System group container for systemgroup.com.apple.configurationprofiles path is /private/var/containers/Shared/SystemGroup/systemgroup.com.apple.configurationprofiles and [MC] Reading from public effective user settings.
App crashes after dismiss pickerController for 1-2 seconds.
and the console says -[AVCaptureSession release]: message sent to deallocated instance 0x1c4201080
Privacy keys already added:
and the related code sample:
func seletedImage() {
let alertAction = UIAlertController.init(title: nil, message: nil, preferredStyle: .actionSheet)
alertAction.addAction(UIAlertAction.init(title: "拍照", style: .default, handler: { [weak self] (alertCamera) in
self?.showImagePicker(sourceType: .camera)
}))
alertAction.addAction(UIAlertAction.init(title: "从相册中选择", style:.default, handler: { [weak self] (alertPhpto) in
self?.showImagePicker(sourceType: .photoLibrary)
}))
alertAction.addAction(UIAlertAction.init(title: "取消", style: .cancel, handler: nil))
self.present(alertAction, animated: true, completion: nil)
}
func showImagePicker(sourceType: UIImagePickerControllerSourceType) {
if UIImagePickerController.isSourceTypeAvailable(sourceType) == false {
if sourceType == .camera { print("未授予使用相机权限") }
if sourceType == .photoLibrary { print("未授予访问相册权限") }
return
}
let picker: UIImagePickerController = UIImagePickerController()
picker.delegate = self as UIImagePickerControllerDelegate & UINavigationControllerDelegate
picker.sourceType = sourceType
picker.allowsEditing = false
weak var weakself = self
weakself?.present(picker, animated: true, completion: nil)
}
am I missing some other important configurations?
maybe something related to GPUImage?
any help is really really appreciate.
PS. it crashes even I don't take a picture and just cancel directly. the photoLibrary type works fine.

Please handle a case that camera is not available . Please use below code
func SelectFromCamera() {
//Camera
let cameraMediaType = AVMediaTypeVideo
AVCaptureDevice.requestAccess(forMediaType: cameraMediaType) { granted in
if granted {
print("Granted access to \(cameraMediaType)")
if UIImagePickerController.isSourceTypeAvailable(
UIImagePickerControllerSourceType.camera) {
let imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType =
UIImagePickerControllerSourceType.camera
imagePicker.mediaTypes = ["public.image"]
// imagePicker.allowsEditing = false
self.present(imagePicker, animated: true,
completion: nil)
}
} else {
//open app setting if not authorize to access camera
print("Denied access to \(cameraMediaType)")
}
}
}
