I've got the same problem on a Vernee Thor. I extracted the error stack trace (@devs you can fin it bellow). It seems that the actual code doesn't properly handle multi fingerprints. You can suppress all the fingerprints from the security settings of Android and only add one for now. It did the trick for me. Hope it helps others. 2019-05-27 18:23:27.584 22246-22246/?
