AllowAlternativeAuthentication + Samsung SM-M307FN quit app

[matteopiccioni]

Steps to reproduce

Hello, I have a Samsung SM-M307FN (Android 10) with finger id and face id enabled. Using Plugin.Fingerprint 2.1.1, Xamarin Form 4.8.0.1451

If I use AllowAlternativeAuthentication=true then the app shows me the authentication popup (with finger and code option) and the app crashes at var result = await CrossFingerprint.Current.AuthenticateAsync(dialogConfig);

If I use AllowAlternativeAuthentication = false then the app works in the right way and show me the authentication popup (with finger and face option).

Expected behavior

The app should works with AllowAlternativeAuthentication = true

Actual behavior

The app crashes
