Is this suited for github?

  • Yes, this is suited for github

To Reproduce

  1. Build a production iOS app with @better-auth/expo using expo-secure-store as storage
  2. Install via TestFlight (fresh install, not an update)
  3. Tap Google or Apple sign-in
  4. App crashes immediately

Current vs. Expected behavior

Current behavior

On a fresh production install (TestFlight), tapping Google or Apple sign-in causes an immediate native crash (SIGABRT in ObjCTurboModule::performVoidMethodInvocation). The app terminates without any JS error being catchable.

After force-closing and reopening the app, the exact same sign-in flow works perfectly.

This only happens on production builds (developmentClient: false). Development builds never crash.

Expected behavior

Social sign-in should work on the very first launch of a fresh production install, without requiring the user to force-close and reopen the app.

What version of Better Auth are you using?

1.4.17
