Gradle caching can sometimes cause conflicts. To resolve this, clear the Gradle caches by deleting the ~/.gradle/caches directory. This forces Gradle to download fresh dependencies.
Ensure Compatibility
Verify that the Android Gradle Plugin version is compatible with your Kotlin version. Refer to the Kotlin documentation for compatibility details.
