Phi Silica - LanguageModel.CreateAsync() throws Exception

[harvinders]

Describe the bug

I am on X Plus, with dev channel OS (26120.3073), WinUI packaged app

I am getting exception whilst creating the model LanguageModel.CreateAsync();

           if (!LanguageModel.IsAvailable())
           {
               var op2 = await LanguageModel.MakeAvailableAsync();
           }

           try
           {
               using LanguageModel languageModel = await LanguageModel.CreateAsync();

               string prompt = "Provide the molecular formula for glucose.";

               var result = await languageModel.GenerateResponseAsync(prompt);

               Console.WriteLine(result.Response);
           }
           catch (Exception e)
           {
           }

@harvinders I at least can't immediately spot what's going wrong. Would you mind grabbing a repro mode Feedback Hub trace of the problem? You can use "Developer Platform -> Windows Copilot Runtime" as the category. It should have a 'Share' option for you to grab an aka.ms link to the item.
