Hi there, We recently released our app and got one production crash that can not be reproduced by our developers. It happens only on iOS 17.5.1 and the crash seems to be related to STWebpageController init at app start. The crash number is increasing fast but we have no idea about why it happens. Please help us to check the crash report below: Role: Foreground OS Version: iPhone OS 17.5.1 (21F90) Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Termination Reason: SIGNAL 6 Abort trap: 6 Triggered by Thread: 0 Last Exception Backtrace: 0 CoreFoundation 0x1a29fcf20 __exceptionPreprocess + 164 (NSException.m:249) 1 APP_NAME 0x105e9e344 crashpad::(anonymous namespace)::HANDLE_UNCAUGHT_NSEXCEPTION(objc_object*, char const*) + 700 (exception_processor.mm:306) 2 APP_NAME 0x105e9d640 crashpad::(anonymous namespace)::ObjcExceptionPreprocessor(objc_object*) + 2544 (exception_processor.mm:513) 3 libobjc.A.dylib 0x19a8a6018 objc_exception_throw + 60 (objc-exception.mm:356) 4 Foundation 0x1a1f03868 -[NSAssertionHandler handleFailureInMethod:object:file:lineNumber:description:] + 188 (NSException.m:252) 5 ScreenTime 0x226860b2c __31-[STWebpageController loadView]_block_invoke + 448 (STWebpageController.m:140) 6 UIKitCore 0x1a55ae418 __146-[NSExtension(UIViewControllerAdditions) _instantiateViewControllerWithInputItems:asAccessory:traitCollection:listenerEndpoint:connectionHandler:]_block_invoke.29 + 268 (NSExtension_UIKitAdditions.m:96) 7 libdispatch.dylib 0x1aa8a013c _dispatch_call_block_and_release + 32 (init.c:1530) 8 libdispatch.dylib 0x1aa8a1dd4 _dispatch_client_callout + 20 (object.m:576) 9 libdispatch.dylib 0x1aa8b05a4 _dispatch_main_queue_drain + 988 (queue.c:7898) 10 libdispatch.dylib 0x1aa8b01b8 _dispatch_main_queue_callback_4CF + 44 (queue.c:8058) 11 CoreFoundation 0x1a29cf710 __CFRUNLOOP_IS_SERVICING_THE_MAIN_DISPATCH_QUEUE__ + 16 (CFRunLoop.c:1780) 12 CoreFoundation 0x1a29cc914 __CFRunLoopRun + 1996 (CFRunLoop.c:3149) 13 CoreFoundation 0x1a29cbcd8 CFRunLoopRunSpecific + 608 (CFRunLoop.c:3420) 14 GraphicsServices 0x1e787c1a8 GSEventRunModal + 164 (GSEvent.c:2196) 15 UIKitCore 0x1a500490c -[UIApplication _run] + 888 (UIApplication.m:3713) 16 UIKitCore 0x1a50b89d0 UIApplicationMain + 340 (UIApplication.m:5303) 17 APP_NAME 0x104dbc5c0 AppMain + 444 (app_exe_main.mm:128) 18 APP_NAME 0x104dbc630 main + 12 (app_exe_main.mm:135) 19 dyld 0x1c607de4c start + 2240 (dyldMain.cpp:1298) Thread 0 Crashed: 0 libsystem_kernel.dylib 0x00000001ebab742c __pthread_kill + 8 (:-1) 1 libsystem_pthread.dylib 0x00000001ff856c0c pthread_kill + 268 (pthread.c:1721) 2 libsystem_c.dylib 0x00000001aa95aba0 abort + 180 (abort.c:118) 3 libc++abi.dylib 0x00000001ff774ca4 abort_message + 132 (abort_message.cpp:78) 4 libc++abi.dylib 0x00000001ff764e5c demangling_terminate_handler() + 348 (cxa_default_handlers.cpp:77) 5 libobjc.A.dylib 0x000000019a8c1e2c _objc_terminate() + 144 (objc-exception.mm:496) 6 ourSdk 0x0000000108d8bc40 FIRCLSTerminateHandler() + 500 (FIRCLSException.mm:0) 7 libc++abi.dylib 0x00000001ff774068 std::__terminate(void (*)()) + 16 (cxa_handlers.cpp:59) 8 libc++abi.dylib 0x00000001ff77400c std::terminate() + 108 (cxa_handlers.cpp:88) 9 libdispatch.dylib 0x00000001aa8a1de8 _dispatch_client_callout + 40 (object.m:579) 10 libdispatch.dylib 0x00000001aa8b05a4 _dispatch_main_queue_drain + 988 (queue.c:7898) 11 libdispatch.dylib 0x00000001aa8b01b8 _dispatch_main_queue_callback_4CF + 44 (queue.c:8058) 12 CoreFoundation 0x00000001a29cf710 __CFRUNLOOP_IS_SERVICING_THE_MAIN_DISPATCH_QUEUE__ + 16 (CFRunLoop.c:1780) 13 CoreFoundation 0x00000001a29cc914 __CFRunLoopRun + 1996 (CFRunLoop.c:3149) 14 CoreFoundation 0x00000001a29cbcd8 CFRunLoopRunSpecific + 608 (CFRunLoop.c:3420) 15 GraphicsServices 0x00000001e787c1a8 GSEventRunModal + 164 (GSEvent.c:2196) 16 UIKitCore 0x00000001a500490c -[UIApplication _run] + 888 (UIApplication.m:3713) 17 UIKitCore 0x00000001a50b89d0 UIApplicationMain + 340 (UIApplication.m:5303) 18 APP_NAME 0x0000000104dbc5c0 AppMain + 444 (app_exe_main.mm:128) 19 APP_NAME 0x0000000104dbc630 main + 12 (app_exe_main.mm:135) 20 dyld 0x00000001c607de4c start + 2240 (dyldMain.cpp:1298)
