Adding -keep class androidx.lifecycle.DefaultLifecycleObserver proguard rule fixes this problem

Still having the issue in 4.9.0.
please add this to documentation -keep class androidx.lifecycle.DefaultLifecycleObserver if this is not gonna be fixed. Lost a lot of time because of this.

Same for me, was forced downgrade to 4.8.2 instead.
Will add -keep class androidx.lifecycle.DefaultLifecycleObserver to proguard and check if this gonna work
