Review your build.gradle files for any conflicting dependencies or version mismatches.
dependencies {
implementation 'androidx.appcompat:appcompat:1.2.0' // Example
implementation 'com.google.android.material:material:1.3.0' // Example
// ... other dependencies
}
5. Ensure Proper JDK Configuration
Verify that your JDK version is compatible with Android Studio and your project requirements.
6. Clear the Gradle Cache
