The NoClassDefFoundError for EnumEntriesKt occurs because the new UI version 2.9 requires Kotlin version 1.8.20 or higher.

Update the Kotlin plugin version in your project’s root build.gradle file to at least 1.8.20 (or higher, such as 1.9.0).

Apply the Kotlin plugin in your app’s build.gradle file:

```

apply plugin: 'org.jetbrains.kotlin.android'

```
