I'm seeing the same thing. I see you've asked your question a year ago. Were you able to fix your issue since then?

I'm seeing this as well. Cancelling a video export a couple of times freezes the app (iOS 16.1.1)

I've created FB12006175 to track this

I'm seeing this issue as well on Xcode Version 14.2 (14C18)

Hi @eskimo, this is caused by a crash in com.apple.dt.Xcode.ITunesSoftwareService. After retrying 4-5 times it works and signs/uploads the app. Thread 5 Crashed:: Dispatch queue: com.apple.NSURLSession-delegate 0 libobjc.A.dylib 0x1866cdc34 objc_msgSend + 52 1 CoreFoundation 0x186bd6f54 ___CFXRegistrationPost_block_invoke + 124 2 CoreFoundation 0x186bd6e78 _CFXRegistrationPost + 440 3 CoreFoundation 0x186b0c580 _CFXNotificationPost + 704 4 Foundation 0x187a699e4 -[NSNotificationCenter postNotificationName:object:userInfo:] + 88 5 Notarization 0x1061cb69c 0x1061a8000 + 145052 6 Notarization 0x1061dfcd8 0x1061a8000 + 228568 7 Notarization 0x1061dd490 0x1061a8000 + 218256 8 CFNetwork 0x18b38c56c 0x18b2cb000 + 791916 9 CFNetwork 0x18b31f6dc 0x18b2cb000 + 345820 10 libdispatch.dylib 0x1868b6874 _dispatch_call_block_and_release + 32 11 libdispatch.dylib 0x1868b8400 _dispatch_client_callout + 20 12 libdispatch.dylib 0x1868bfa88 _dispatch_lane_serial_drain + 668 13 libdispatch.dylib 0x1868c062c _dispatch_lane_invoke + 436 14 libdispatch.dylib 0x1868cb244 _dispatch_workloop_worker_thread + 648 15 libsystem_pthread.dylib 0x186a64074 _pthread_wqthread + 288 16 libsystem_pthread.dylib 0x186a62d94 start_wqthread + 8 another crash: Thread 2 Crashed:: Dispatch queue: com.apple.NSXPCConnection.user.anonymous.62440 0 libobjc.A.dylib 0x1866cc5f8 objc_release + 16 1 DVTITunesSoftwareServiceFoundation 0x100fb4fbc NotarizationWrapper.getStatus(submissionID:authenticationServiceIdentifier:accountCredentials:teamID:extraHeaders:) + 1360 2 DVTITunesSoftwareServiceFoundation 0x100fb5710 @objc NotarizationWrapper.getStatus(submissionID:authenticationServiceIdentifier:accountCredentials:teamID:extraHeaders:) + 252 3 com.apple.dt.Xcode.ITunesSoftwareService 0x100e3aee4 -[DVTITunesSoftwareService notarizationStatusResponse:accountCredentials:teamID:authenticationServiceIdentifier:extraHeaders:callback:] + 260 4 CoreFoundation 0x186b288a4 __invoking___ + 148 5 CoreFoundation 0x186b28718 -[NSInvocation invoke] + 428 6 Foundation 0x187b0b384 __NSXPCCONNECTION_IS_CALLING_OUT_TO_EXPORTED_OBJECT__ + 16 7 Foundation 0x1880e542c -[NSXPCConnection _decodeAndInvokeMessageWithEvent:reply:flags:] + 1204 8 Foundation 0x1880e6da4 message_handler_message + 88 9 Foundation 0x1880e6810 message_handler + 152 10 libxpc.dylib 0x1867abe74 _xpc_connection_call_event_handler + 152 11 libxpc.dylib 0x1867aa8f4 _xpc_connection_mach_event + 1376 12 libdispatch.dylib 0x1868b84c0 _dispatch_client_callout4 + 20 13 libdispatch.dylib 0x1868d4ed8 _dispatch_mach_msg_invoke + 468 14 libdispatch.dylib 0x1868bf960 _dispatch_lane_serial_drain + 372 15 libdispatch.dylib 0x1868d5c24 _dispatch_mach_invoke + 448 16 libdispatch.dylib 0x1868bf960 _dispatch_lane_serial_drain + 372 17 libdispatch.dylib 0x1868c062c _dispatch_lane_invoke + 436 18 libdispatch.dylib 0x1868cb244 _dispatch_workloop_worker_thread + 648 19 libsystem_pthread.dylib 0x186a64074 _pthread_wqthread + 288 20 libsystem_pthread.dylib 0x186a62d94 start_wqthread + 8
