Hello Everyone,

I got this crash in Crashlytics of iOS App Store Build (project is made in Unity & React-native). The crash is not reproducable as it is not appearing in dev build. Any help is highly appreciated.

Here is the version we used:-

Unity Version: 2018.2.14f1.
React Version: 16.3.1
React-native version: 0.55.4
XCode version: 10.1

Here is the crash log:-
