Platform: iOS

How do you use Sentry? Sentry SaaS (sentry.io)

Configuration:

Sentry.init({
      dsn: "https://xxxxxxxxx.xxxx.sentry.io/xxxxx",
      //Enable Instrumentation
      integrations: [
        new Sentry.ReactNativeTracing({
          routingInstrumentation: reactNavigationV4Instrumentation,
          tracingOrigins: ['localhost', 'xxxxx.xxx.xxx', /^\//, /^https:\/\//],
        }),
      ],
      tracesSampleRate: 1,
      environment: isEmulator ? `${Config.SENTRY_ENV}_simulator` : Config.SENTRY_ENV,
    });

Steps to Reproduce

Previously we were using v2.6.2 and after upgrading to @sentry/react-native v3.2.3, we are experiencing a hard application crash when launching our application with the above Sentry.init

I tried all the version from 3.2.3 to 3.2.8 but issue is still happening. After downgrading to 2.6.2 I am not observing this issue.Because of this I am not able to upgrade to 3.x

issue is only happening on iOS (easily reproducible on iOS 12.5.5 )and its not consistent. If I launch the application 4 to 5 times then one of the launch is crashing. We are observing this issue on iOS 12 and iOS 14

Expected Result

Application runs as normal

Actual Result

Application closes immediately upon load of the compiled JS bundle. I have shared the issue link

@marandaneto Give me weeks time. I will provide the minimal reproducible example repo.

@marandaneto, can we bump sentry-cocoa to 7.10.2 and see if it fixes this problem as we released https://github.com/getsentry/sentry-cocoa/pull/1692 with it.
