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 also observed similar crash in IFingerprintService.cancelAuthentication(IFingerprintService.java:320)

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):
