Prebuild step fails because it updates the yarn.lock file (managed)

Expo Application Services (EAS)

Posting related build logs below.

The project is a managed expo project and it replaces the react-native dependency when installing which updates the lock-file and then exits with an error. Anyone know why this is happening and how I can mitigate it?

Prebuilding managed project
- Creating native project directories (./ios and ./android) and updating .gitignore
✔ Created native project
- Adding Metro bundler config
⚠️  Skipped Metro config updates:
› Existing Metro config found; not overwriting.
› You will need to extend the default @expo/metro-config in your Metro config.

- Updating your package.json scripts, dependencies, and main file
✔ Updated package.json and added index.js entry point for iOS and Android
- Config syncing
✔ Config synced

yarn 2 enables immutable option by default when running on CI (e.g. if CI env is set) you can override it by specifying env in your eas.json build profile "YARN_ENABLE_IMMUTABLE_INSTALLS": "false"
