Android DataStore: unresolved Reference edit, stringPreferencesKey

I'm writing an Android app that is using DataStore. I'm failing to compile even a stripped-down version of it - I always get a compilation error for the import statements saying unresolved Reference to edit, stringPreferencesKey and so on of PreferenceDataStore:

Task :app:compileDebugKotlin FAILED

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        val user = "Frank"
        lifecycleScope.launch {
            this@MainActivity.dataStore.edit {
                it[DS_USER] = user
            }
        }

        setContent {
            Surface(modifier = Modifier.fillMaxSize()) {
                Text("Hallo")
            }
        }
    }
}

build.gradle.kts (dependency group):

}

I stripped-down the app as far as possible and checked the gradle file. I'm using the latest version of 1.1.5 for androidx.datastore:datastore-preferences and the latest Kotlin version kotlin = "2.1.20".

This seem to only happen when building the app, the built-in compiler of Android Studio doesn't show any issues. This also seems to be exclusive to clean builds with data store version 1.1.5.

My build environment is up to date - I'm completely clueless.

This seems to be an issue with Datastore 1.1.5, downgrading androidx.datastore:datastore-preferences to 1.1.4 should solve the issue until this is fixed.
