Hi @gsgou. How are you?

While I can propose some solutions, unfortunately, I'm unable to reproduce this issue. Let me ask a few questions first:

• Which version of the plugin are you using?
• Does it throw any exceptions if you enable ThrowErrors = true?

[JairoMarques]

Same crash here!

Using versioin 1.2.3

It doesn't throw any exception.

The program 'SescApp.dll' has exited with code 0 (0x0).

My code:
private async Task CheckAuthAndInitAsync()
{
var oauthToken = await HelperService.GetSecureStorageKeyAsync("oauth_token");
var token = Token.ValidateToken(oauthToken);

    if (string.IsNullOrEmpty(token))
    {

        _navigatingToLogin = true;

        await MainThread.InvokeOnMainThreadAsync(async () =>
        {
            // deixa o Shell “respirar” e evita navegação durante o layout
            await Task.Yield();

            // rota registrada via Routing.RegisterRoute
            await Shell.Current.GoToAsync("Login", true);
        });

        return;
    }

    _navigatingToLogin = false;

    // Só executa o resto quando autenticado

            _screenSecurity.ActivateScreenSecurityProtection();
        }
        catch (Exception ex)
        {
            // Handle the exception here...

    }

    // Attach to the ScreenCaptured event handler
    _screenSecurity.ScreenCaptured += OnScreenCaptured;

    if (carouselView.CurrentItem is Cartao cliente)

    _screenSecurity.DeactivateScreenSecurityProtection();

    // Detach from the ScreenCaptured event handler
    _screenSecurity.ScreenCaptured -= OnScreenCaptured;

    base.OnDisappearing();

    ((CredentialViewModel)BindingContext).OnDisappearing();
}
private async void OnScreenCaptured(object? sender, EventArgs e)

    string title = "Sesc";
    string message = "A captura desta tela está desabilitada.";

I changed to loaded event in iOS and solved the problem:

private async void CredentialView_Loaded(object? sender, EventArgs e)
{
#if IOS
if (_navigatingToLogin) return;

    _screenSecurityCts?.Cancel();
    _screenSecurityCts = new CancellationTokenSource();
    var ct = _screenSecurityCts.Token;

    await Task.Yield();
    await Task.Delay(200, ct);

    if (ct.IsCancellationRequested) return;

    try
    {
        if (!_screenSecurity.IsProtectionEnabled)
        {
            _screenSecurity.ActivateScreenSecurityProtection();
            _screenSecurityActive = true;
        }

        _screenSecurity.ScreenCaptured -= OnScreenCaptured;
        _screenSecurity.ScreenCaptured += OnScreenCaptured;
    }
    catch (Exception ex)
    {
        System.Diagnostics.Debug.WriteLine($"ScreenSecurity activate failed: {ex}");
    }
#endif
}

@JairoMarques I'll close this issue then as seems to not be related with the library.
