I have a code which is download a JSON file and binding it to a CollectionView source.

It's showing as expected in debug. When I build the application and run it stand alone it's showing 10 empty boxes in my collection view (10 as that's my expected JSON result limit). I can click the 10 empty grids but no text is showing. It does in debug

what on earth is wrong?


Code:
public partial class PlayerListViewModel : ObservableObject
{

    [ObservableProperty]
    public string text = "";

    public PlayerListViewModel() {
        PlayerListItems = new ObservableCollection<Player>();
    }

    [ObservableProperty]
    ObservableCollection<Player> playerListItems;


    [RelayCommand]
    public void View()
    {
    
    }


    HttpClient _httpClient = new HttpClient();
    string _url = "https://mydomain.com/all-players.php";


[RelayCommand]
async Task getPlayersAPI()
{

        PlayerListItems.Clear();

        var response = await _httpClient.GetAsync(_url);
        var responseString = await response.Content.ReadAsStringAsync();
        var playerListItems = JsonSerializer.Deserialize<List<Player>>(responseString);
        
        Text = responseString.ToString();
        

        foreach (var item in playerListItems)
        {
            PlayerListItems.Add(item);
        }
    

}
