Do you know what device(s) this is happening on? Looks like it's crashing in the framework code perhaps in autogenerated binder code.
android.hardware.fingerprint.IFingerprintService$Stub$Proxy.authenticate(IFingerprintService.java:341)

We're also seeing this occasionally - we've seen the FingerprintHelperFragment stack trace reported above, as well as this slightly different one (they all have the same underlying cause):

Re-assigning to curtis, since Grace merged a fix for the original bug. I think Curtis is adding some additional NPE checks before closing
Description
Library version: 1.0.0-alpha03
When setting a new NavGraph to NavController, the back stack is not resetted.
From the documentation, "Any current navigation graph data will be replaced."
If a NavGraph is already setted then the back stack containts the default destination. In calling NavGraph.setGraph(NavGraph) and in the new graph, the destination is different, then the new destination is not displayed because back stack is not resetted.
Is it expected feature or not?
