Why am I getting SecurityException in WearableActivityController.onDestroy in WearOS on Samsung Watch 4?

Question

This exception happens when a parent class is called from my WearOS main activity derived from WearableActivity:

class MainActivity() : WearableActivity(),
        CapabilityClient.OnCapabilityChangedListener {
    ...
      override fun onDestroy() {
    super.onDestroy() // <--- Here !!!

    if (mApp?.receiver != null) {
        Util.d(TAG, "UNREG " + mApp?.receiver)
        androidx.localbroadcastmanager.content.LocalBroadcastManager.getInstance(this).unregisterReceiver(mApp!!.receiver!!)
        mApp!!.receiver = null
    }
}

The full stack trace from Google Play is below. The watch model is Samsung Watch 4 running Android 11. I didn't see the crash on other watches.

I don't think (not100% sure) the WearableActivityController is expected to be used in a modern Wear app. Is it from com.google.android.wearable:wearable:2.9.0?

Are you using it for ambient support? If so look at https://github.com/android/wear-os-samples/blob/main/AlwaysOnKotlin/views/src/main/java/com/example/android/wearable/wear/alwayson/MainActivity.kt
