Summary: When running with the packager in the tvOS simulator, reloading from the packager hits an assert in `RCTEventEmitter`, causing a crash. The solution is for `RCTTVNavigationEventEmitter` to check for the existence of the bridge before attempting to send an event. Manual testing. [IOS] [BUGFIX] [RCTTVNavigationEventEmitter.m] - Fix crash when reloading in tvOS Closes https://github.com/facebook/react-native/pull/17797 Differential Revision: D7014975 Pulled By: hramos fbshipit-source-id: 0bf766e87267ca8592ff0cc0b3cb4621a8e8f9b5
