Can’t locate source of fatal exception due to obfuscation in React Native app

I am trying to debug a crash reported by Firebase Crashlytics found in the latest version of my app.

The error seems somewhat obfuscated (despite having uploaded a ProGuard mapping file) and based on the vagueness of the error I am struggling to pinpoint the issue.

I fully understand the Text strings must be rendered within a <Text> component error description – but this error didn’t show up in testing and seems to be something to do with the latest release build.

If anyone knows any tips as to how I can pinpoint where this fatal exception is occurring, I would appreciate it.

All I can determine is that the error occurs in a subview of a ScrollView component. Is there anything else that can be taken from this message to help me determine the cause?
