App crashed on TestFlight mode build with react native expo

I have created an App ,tested on simulator and works very well. Developed using react native expo. But after creating an TestFlight mode for testing , it crashed on startup. I am able to retrieve logs from crashed app, but I could not able to understand anything about cause of this crashed. Any help would be highly appreciated.

Your app has crashed due to an unhandled language exception. To tell you more I need to see the full crash report. Please post it here, following the instructions in Posting a Crash Report.
