Having the same issue on SDK42. { "name": "APPNAME", "version": "0.0.1", "description": "", "author": "", "private": true, "main": "node_modules/expo/AppEntry.js", "scripts": { "start": "expo r -c", "eject": "expo eject", "android": "expo start --android", "ios": "expo start --ios", "test": "jest" }, "dependencies": { "@bugsnag/expo": "6.5.1", "@expo/vector-icons": "^12.0.0", "@react-native-community/slider": "3.0.3", "@react-navigation/bottom-tabs": "^5.11.2", "@react-navigation/material-top-tabs": "5.3.17", "@react-navigation/native": "^5.8.10", "@react-navigation/stack": "^5.12.8", "crypto-js": "^4.0.0", "expo": "^42.0.0", "expo-ads-admob": "~10.1.2", "expo-av": "~9.2.3", "expo-blur": "~9.0.3", "expo-contacts": "~9.2.5", "expo-device": "~3.3.0", "expo-facebook": "~11.3.1", "expo-file-system": "~11.1.3", "expo-firebase-analytics": "~4.1.0", "expo-firebase-core": "~3.1.0", "expo-firebase-recaptcha": "^1.3.0", "expo-font": "~9.2.1", "expo-image-manipulator": "~9.2.2", "expo-image-picker": "~10.2.2", "expo-keep-awake": "~9.2.0", "expo-linking": "~2.3.1", "expo-location": "~12.1.2", "expo-network": "~3.2.0", "expo-permissions": "~12.1.1", "expo-secure-store": "~10.2.0", "expo-sms": "~9.2.3", "expo-updates": "~0.8.2", "firebase": "8.2.3", "lru-cache": "5.1.1", "lunr": "2.3.8", "react": "16.13.1", "react-native": "https://github.com/expo/react-native/archive/sdk-42.0.0.tar.gz", "react-native-country-picker-modal": "^2.0.0", "react-native-crypto-js": "^1.0.0", "react-native-gesture-handler": "~1.10.2", "react-native-keyboard-aware-scroll-view": "^0.9.3", "react-native-pager-view": "5.0.12", "react-native-safe-area-context": "3.2.0", "react-native-safe-area-view": "1.0.0", "react-native-scripts": "2.0.1", "react-native-scrollable-tab-view": "^1.0.0", "react-native-svg": "12.1.1", "react-native-tab-view": "^3.1.1", "react-native-vector-icons": "6.0.2", "react-native-webview": "11.6.2", "react-redux": "7.1.3", "redux": "4.0.0", "yarn": "^1.22.0" }, "devDependencies": { "@babel/core": "~7.9.0", "@react-native-community/masked-view": "0.1.10", "babel": "6.23.0", "babel-plugin-module-alias": "1.6.0", "clamp": "1.0.1", "react-native-screens": "~3.4.0", "schedule": "0.4.0" }, "expo": { "version": "6" } } I used expo upgrade to update the app. I was on SDK39 and now I'm trying to launch SDK42 but my Testflight build crashes immediately. When running in the Expo Go app or the iOS Simulator it loads correctly, no errors.
