When saving the video, if the AddOnly permission is taken first and then the ReadWrite permission is taken, the performChanges method will freeze for more than 10 seconds before calling the completionHandler. The following is the log information: [Generic] Failed to connect to XPC PhotoLibraryStore file:///var/mobile/Media/PhotoData/Photos.sqlite with options { 		NSXPCStoreServerEndpointFactory = "<PLXPCPhotoLibraryStoreEndpointFactory: 0x280700d00>"; These problems only occur during a cold launch when the AddOnly permission is taken first and then the ReadWrite permission is taken. Whether the app only takes the AddOnly permission, only takes the ReadWrite permission, or closes the app after authorization and reopens it will not happen.
