[Expo 49] Android build fails with kotlin version incompatibility error

[sergey-fieldmaterial]

Please provide the following:

1. SDK Version: 49
2. Platforms(Android/iOS/web/all): Android
3. Add the appropriate “Tag” based on what Expo library you have a question on.

After upgrading to Expo SDK 49 I see many errors when building Android project

[RUN_GRADLEW] e: /private/var/folders/zg/bxg4djw17bn_36b658hnp0380000gn/T/eas-build-local-nodejs/67dea9b4-e73e-4cfa-bd2c-8949ecb878c0/build/node_modules/expo-modules-core/android/src/main/java/expo/modules/kotlin/views/ViewTypeConverter.kt: (20, 11): Class ‘kotlin.Unit’ was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.8.0, expected version is 1.6.0.

What could be the root cause and how to fix this issue?
I see that in version 49 there is an upgrade to Gradle 8, but not sure if any external packages needs to be migrated / updated as well?

Thanks!
