Deadlocks whenever calling graphQLClient from Maui

I am really struggling to get any data returned from a GraphQL Query in Maui. I had the code in the initializer of the Page and was hitting Deadlocks. I get that now. So I have move the code to a button on a page. It is hanging on the line below the Task GetDocumentAsync:

var graphQLResponse = await graphQLHttpClient.SendQueryAsync<RootObject>(documentRequest);

The almost similar code works fine in a console app. But I can’t get it to return in the Maui app. No errors, just hangs.

Here is some relevant code:

Button on a page:

MAINPAGE XAML

<VerticalStackLayout Margin="20">
    <Button Text="Load"
            VerticalOptions="Center"
            HorizontalOptions="Center"
            Clicked="OnButtonClicked"/>
    <Entry x:Name="documentId"
           FontSize="24"
           Keyboard="Chat"
           Placeholder="EnterScan Id"
           ClearButtonVisibility="WhileEditing"/>
    <ListView ItemsSource="{Binding ErpDocument}" 
              HasUnevenRows="True" 
              VerticalOptions="FillAndExpand"
              SeparatorColor="Black"
              ItemSelected="OnListItemSelected"
              SelectedItem="{Binding SelectedListItem,Mode=TwoWay}">
        <ListView.BindingContext>
            <viewModels:DocumentViewModel />
        </ListView.BindingContext>
    

CODE-BEHIND

async void OnButtonClicked(object sender, EventArgs args)
{
    DocId key = new DocId();
    key.Id1 = "Default";
    key.Id2 = "WF201B";
    key.Id3 = "000";
    ErpPart erpDocument = ErpPart.Load(key); ;
}
