After I copy it from my external storage into my phone and using : PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: URL) that was successful save into Photo app and the thumbnail at this moment is the first frame of video. After a short period of time, the thumbnail of video auto changes into the other frame.

The debug gives the error: "Operation not permitted" UserInfo={NSLocalizedDescription=Could not create sandbox extension of type com.apple.app-sandbox.read for URL /var/mobile/Media/DCIM/101APPLE/IMG_1416.MOV} which the iOS 14.0 not appear.
