I recently updated my React-Native project (Android and iOS) to version 54 of Expo SDK and react-native 0.81.4. After fixing various issues related to the update, I was able to run the app without any problems on an Android device connected via USB using the command
npx expo run:android.
So far, so good. I encountered problems with the npx expo run:ios command to launch the app on the iOS 18.3 simulator (I tried both on a tablet and a smartphone) or on a physical device by generating a build with EAS and using Expo Go: sometimes the command is successful, the app installs and everything works correctly, but other times it crashes after installation and startup with this message:
