Next steps

I'm currently attempting to deploy a build based on this branch to TestFlight, but I'm facing the app crashing immediately on startup. EAS queues are hours long, so I'm running eas build --local --platform ios --clear-cache --profile preview for local testing on my connected device through Xcode. The iOS crash logs on my device do not clearly show what the issue is. However, because the app runs perfectly fine on the iOS simulator, the crashing threads reference turbomodules, and the app does not even show a screen before crashing, I believe the problem has something to do with installed modules or the translation to native code.
