Jadi, saya mencoba membiarkan pembuatan jetpack berjalan dengan contoh sederhana, saya telah memperbarui plugin kotlin saya menjadi 1.4.0 dan juga memperbarui semua gradle build saya dengan dokumentasi penulisan jetpack, tetapi saya mendapatkan kesalahan ini saat mengompilasi

java.lang.IncompatibleClassChangeError: Ditemukan antarmuka org.jetbrains.kotlin.backend.common.extensions.IrPluginContext, tetapi kelas diharapkan ada di androidx.compose.plugins.kotlin.ComposeIrGenerationExtension.generate (ComposeIrGenerationExtension.kt: 41)

Saya juga telah mengunduh Android studio versi canary

Tapi saya tidak bisa mengkompilasi aplikasi, saya mencoba menjalankan contoh dasar

class MainActivity : AppCompatActivity() {
  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContent{
        sayHello()
    }
  }

  @Preview
  @Composable
  fun sayHello(){
    Text("Hello World")
  }
}

Adakah yang tahu mengapa kesalahan ini dilemparkan?
