We’re in the progress of updating to expo-updates 2.0.0 and as part of that upgrade we’ve stumbled across the the following error when bundling the app in release mode with an image:

We’ve created a reproduction here where the app will work out the box with a yarn install, pod install and built in release mode through Xcode. If you then uncomment the line import Navigation from './src/components/navigation'; and rebuild you will receive the above error.
Note: React Navigation imports images and that’s the problem, the same demo can be reproduced by just importing and using an image in the application. Discussions here: New eject bare workflow unable to load bundled assets on Release configuration and crashes · Issue #1859 · expo/expo-cli · GitHub
Anyone have any suggestions?
