GetStringAsync from HttpClient doesn't return anything C#

Question

We are trying to get information from an API. We use the following code to get an answer. It's a Xamarin Project. We are running it on an Android Emulator with internet connection. Android-Version:11.
When it gets to the line:

var result = await client.GetStringAsync(endpoint);

It just stops and doesn't throw an error. Why is this happening?

private async void Button_Clicked(object sender, EventArgs e)
    {
        var Get = await AsyncGet();
        //await GetItemsAsync();
    }

    public static async Task<string> AsyncGet()
    {
        HttpClientHandler GetInsecureHandler()
        {
            HttpClientHandler handler = new HttpClientHandler();
            handler.ServerCertificateCustomValidationCallback = (message, cert, chain, errors) =>
            {
                if (cert.Issuer.Equals("CN=localhost"))
                    return true;
                return errors == System.Net.Security.SslPolicyErrors.None;
            };
            return handler;
        }
        var client = new HttpClient(GetInsecureHandler());
        try
        {
            var endpoint = new Uri("My Uri");
            var result = await client.GetStringAsync(endpoint);
            var json = JsonConvert.DeserializeObject<string>(result);
            return result;
        }
        catch (Exception ex)
        {
            string checkResult = "Error " + ex.ToString();
            client.Dispose();
            return checkResult;
        }


    }

Alternative code:

async Task<string> GetItemsAsync()
    {
        using (HttpClient client = new HttpClient())
        {
            var response = await client.GetAsync("My Uri");
            return await response.Content.ReadAsStringAsync();
        }


    }

This Code does return the information but only in the console. When it is run with Xamarin, it also doesn't return anything.
