I removed the "react-native-reanimated": "~3.3.0",dependency and it solved my problem. The App was crashing on startup in Test Flight and now is not. This is using expo 49.

I am having the same issue. This application has been released for a couple of years, and has never had this issue. The enhancements are several screens deep into the app and should not impact anything when it opens. I have done error trapping everywhere I can to avoid this issue. I can't help but think it is an updated component that is causing the issue, but I don't have a clue where to look.
