Error code 12 in Biometric Authentication - device have only FaceID

Question

I am doing login validation with Biometric prompt dependency:usedandroidx.biometric:biometric-ktx:1.2.0-alpha04 checked the hardware supported or not using this code

fun isBiometricHardWareAvailable(con: Context): Boolean {
var result = false
val biometricManager = BiometricManager.from(con)

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
    when (biometricManager.canAuthenticate(BiometricManager.Authenticators.DEVICE_CREDENTIAL or BiometricManager.Authenticators.BIOMETRIC_STRONG)) {
        BiometricManager.BIOMETRIC_SUCCESS -> result = true
        BiometricManager.BIOMETRIC_ERROR_NO_HARDWARE -> result = false
        BiometricManager.BIOMETRIC_ERROR_HW_UNAVAILABLE -> result = false
        BiometricManager.BIOMETRIC_ERROR_NONE_ENROLLED -> result = false
        BiometricManager.BIOMETRIC_ERROR_SECURITY_UPDATE_REQUIRED ->
            result = true
        BiometricManager.BIOMETRIC_ERROR_UNSUPPORTED ->
            result = true
        BiometricManager.BIOMETRIC_STATUS_UNKNOWN ->
            result = false
    }
} else {
    when (biometricManager.canAuthenticate()) {
        BiometricManager.BIOMETRIC_SUCCESS -> result = true
        BiometricManager.BIOMETRIC_ERROR_NO_HARDWARE -> result = false
        BiometricManager.BIOMETRIC_ERROR_HW_UNAVAILABLE -> result = false
        BiometricManager.BIOMETRIC_ERROR_NONE_ENROLLED -> result = false
        BiometricManager.BIOMETRIC_ERROR_SECURITY_UPDATE_REQUIRED -> result = false
        BiometricManager.BIOMETRIC_ERROR_UNSUPPORTED -> result = false
        BiometricManager.BIOMETRIC_STATUS_UNKNOWN -> result = false
    }
}
return result}
