IllegalStateException

Hi,
First of all thanks for the repo, I love it.
I'm here just to report, I think, a bug of my code or maybe from the repo.
I have the problem in many devices, and all throw this stack:

java.lang.IllegalStateException:

Just to clarify, this defect is major:

1. Turn the screen OFF and ON while the fingerprint dialogue is open -- app crashes
2. Task away to the home screen while the fingerprint dialogue is open -- app crashes
