int java.util.List.size()' on a null object reference com.exxbrain.android.biometric.BiometricFragment.onCreateView

Hello,
I have some fatal crashes occurring just after users putting their finger on sensor on Motorola Devices,
I can see them on CrashLytics (only for Motorola, for many devices g4 g5 g6 g7 g7 power, plus, etc...)

Fatal Exception: java.lang.NullPointerException

Is there any fix for that issue? I tried to find it but doesn't seem to be application side code
