NlpLocBackendHelper: android.os.DeadObjectException

Using UnifiedNlp on Android 8.1 my log is filled with:

Is there a way to get more debugging what is causing this?

I'm using the package from F-Droid.

Start with the reported call path in org.microg.nlp.location.BackendHelper.java, BackendFuser.java, and ThreadHelper.java, especially BackendHelper.update at line 71. Trace the LocationBackend update call and Android Binder failure to determine what additional debugging information is needed. Done means identifying the source of the DeadObjectException or documenting a reproducible diagnostic path.
