Just updated Android Studio to Bumblebee Canary 4, created a new project and got this error after launching the app
`java.lang.AbstractMethodError: abstract method "void androidx.lifecycle.DefaultLifecycleObserver.onCreate(androidx.lifecycle.LifecycleOwner)"`
I'm using compose 1.0.0-rc02 and activity 1.3.0-rc02. Does anyone know what's wrong? :thread:
