Several users are seeing a crash in a new app version that introduces the use of a UITabBarController. We haven't been able to isolate the crash to a specific user flow, device, or OS version. Fatal Exception: NSInternalInconsistencyException Inconsistency in UITabBar items and view controllers detected. No view controller matches the UITabBarItem '<UITabBarItem: 0x130623160> title='Today' image=<UIImage:0x3001893b0 named(RootTab-resources: today) {36, 32} renderingMode=automatic(original)> selected'. 0 CoreFoundation 0x83f20 __exceptionPreprocess 1 libobjc.A.dylib 0x16018 objc_exception_throw 2 Foundation 0x6de868 _userInfoForFileAndLine 3 UIKitCore 0x85c9d8 -[UITabBarController _viewControllerForTabBarItem:] 4 UIKitCore 0x85ca80 -[UITabBarController _tabBarItemClicked:] 5 UIKitCore 0x3fb31c -[UIApplication sendAction:to:from:forEvent:] 6 UIKitCore 0x785d18 -[UITabBar _sendAction:withEvent:] 7 UIKitCore 0x3fb31c -[UIApplication sendAction:to:from:forEvent:] 8 UIKitCore 0x3fb1f4 -[UIControl sendAction:to:forEvent:] 9 UIKitCore 0x3fb044 -[UIControl _sendActionsForEvents:withEvent:] 10 UIKitCore 0x787054 -[UITabBar _buttonUp:] 11 UIKitCore 0x3fb31c -[UIApplication sendAction:to:from:forEvent:] 12 UIKitCore 0x3fb1f4 -[UIControl sendAction:to:forEvent:] 13 UIKitCore 0x3fb044 -[UIControl _sendActionsForEvents:withEvent:] 14 UIKitCore 0x913894 -[UIControl touchesEnded:withEvent:] 15 UIKitCore 0x33beac -[UIWindow _sendTouchesForEvent:] 16 UIKitCore 0x33b954 -[UIWindow sendEvent:] 17 UIKitCore 0x1bc9e0 -[UIApplication sendEvent:] 18 UIKitCore 0x1be1d4 __dispatchPreprocessedEventFromEventQueue 19 UIKitCore 0x1c6ecc __processEventQueue 20 UIKitCore 0xb984c updateCycleEntry 21 UIKitCore 0xb776c _UIUpdateSequenceRun 22 UIKitCore 0xb73b0 schedulerStepScheduledMainSection 23 UIKitCore 0xb8254 runloopSourceCallback 24 CoreFoundation 0x56834 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ 25 CoreFoundation 0x567c8 __CFRunLoopDoSource0 26 CoreFoundation 0x54298 __CFRunLoopDoSources0 27 CoreFoundation 0x53484 __CFRunLoopRun 28 CoreFoundation 0x52cd8 CFRunLoopRunSpecific 29 GraphicsServices 0x11a8 GSEventRunModal 30 UIKitCore 0x40a90c -[UIApplication _run] 31 UIKitCore 0x4be9d0 UIApplicationMain 32 Coach 0x62a44 main + 14 (main.m:14) 33 ??? 0x1bcfd9e4c (Missing) I have only found 2 references to this exception online and neither of them have a resolution: https://stackoverflow.com/questions/77536249/embed-flutterviewcontroller-to-native-swift-tabbar https://github-com.translate.goog/ChenYilong/CYLTabBarController/issues/608?_x_tr_sl=zh-CN&_x_tr_tl=en&_x_tr_hl=en&_x_tr_pto=sc Any ideas on how this can be further investigated or resolved?

I've started seeing several users getting an app crash that I've been unable to find the root cause for so far. I've tried running the app in release build with address sanitizer and zombie objects checks enabled but have been unable to reproduce it. It only occurs for iOS 17 users. Any ideas on how I can troubleshoot this?
