I wonder if it has to do with this:

react-native-fingerprint-scanner/android/src/main/java/com/hieuvp/fingerprint/ReactNativeFingerprintScannerModule.java

Lines 98 to 101 in 31f160f

	// memoize so can be accessed to cancel
	if (biometricPrompt != null) {
	return biometricPrompt;
	}

The way all the biometric stuff works changed with android API28 (Android P) and you don't specify what device under test is running, this guess is for >= 28

I could not find any relevant issues on stackoverflow which is usually an indicator that platform API usage is incorrect, stated differently - the code here may not be 100%, you might be on to something
