I have a React Native (0.59.8) app that works perfectly fine on simulator, perfectly fine when deployed to device through Xcode, but unresponsive when distributed over TestFlight for about 3 minutes on app start only if the user hasn't logged in.

Here is what happens:

• I install my app through TestFlight
• Open the app.
• There is a 'get started' button on welcome page, that takes the user to the login screen. I tap that button
• Nothing happens for about 2-3 minutes
• App goes to the login screen and everything starts working perfectly.

Some observations:

• This happens only on TestFlight archive builds, it doesn't happen on simulator or when deployed through Xcode > Run.
• This happens on multiple physical devices (though both a iPhone X, we currently don't have any other devices to test).
• When app is in that "crashed" state, rotating my phone rotates everything perfectly to landspace orientation. i.e., the app is actually running and responding/layouting correcty to rotations. Though, the tab bar icon layout atht the bottom doesn't change correctly to the landscape/portraint orientation.
• If the user isn't logged in inside my app, and I kill the app and relaunch, same problem occurs.
• Once the user is logged in everything works.
• If I kill the app and relaunch when the user is logged in, I get my homepage that is inside a tab bar and has some tappable views. The scroll view scrolls perfectly and smoothly BUT tab bar buttons and tappable links don't work. When I let it stay on for a few minutes, it crashes with the following log from my iPhone in Console.app:

When I follow the instruction from https://reactnavigation.org/docs/en/getting-started.html

and run the application, I have this error

Requiring module "node_modules/react-native-gesture-handler/index.js", which threw an exception: TypeError:

When using react-native-web NetInfo works fine for Android and iOS but is not working for web.

To confirm the code being run for web is the same as Android I console log in the componentDidMount and both Android and Web display the text. However the events dont seem to be working for the web version.

I am trying to build a barcode scanner web app. I found some code samples online but when I run yarn start-web I get the following error:

Failed to compile.

./node_modules/expo/build/Notifications/Notifications.js Attempted import error: 'DeviceEventEmitter' is not exported from 'react-native'.

Here is the issue with npm start, running react-scripts start. Please, could anyone help me with it?

I am trying to use Swiper in my app and I am getting this Error on console.

!UPDATED: added code where the swiper is used.
