"Unhandled JS Exception: TypeError: null is not an object (evaluating '(n=t.NativeModules.UMReactNativeEventEmitter).addProxiedListener')

[Yandamuri]

I migrated my app from react-native-unimodules to Expo by following this guide -- https://github.com/expo/fyi/blob/main/expo-modules-migration.md

App is getting crashed while trying to install codepush updates. Here is the crash message form Xcode,

Here is the Crash report from Firebase Crashlytics,

Fatal Exception: RCTFatalException: Unhandled JS Exception: TypeError: null is not an object (evaluating '(n=t.NativeModules.UMReactNativeEventEmitter).addProxiedListener')

Here are few important points to notice,

1. Release Mode --> App crashes while trying to install codepush updates.

2. Debug Mode -- > There is no crash while trying to install codepush updates.

This crash is occurring apparently after I migrated from react-native-unimodules to Expo.
