Problem using DisplayAlert

[AMT-Cheif]

I need to show a display allert if a value is zero; I have to call it from a sync method, so I do:

Task.Run(async () =>
{
    await ShowAlertAsync();
}).Wait();

public async Task ShowAlertAsync()
  {
      try
      {
        
          await DisplayAlert("Error", "Value can't be.", "OK");
      }
      catch (Exception ex)
      {
          await DisplayAlert("Error", $"An error occurred: {ex.InnerException?.Message ?? ex.Message}", "OK");
      }
  }

but I get: "One or more errors occurred. (Exception has been thrown by the target of an invocation.)" without any details.
Anyone can help please?

Why do you want to use Task.Run()? Did you try calling ShowAlertAsync() directly?
