.Net: Bug: Cannot execute KernelFunctions when using - phi-3 cpu-int4-rtn-block-32

[Vizeo]

Cannot execute KernelFunctions when using - phi-3 cpu-int4-rtn-block-32.

Running the following code should return "Ironman". But the function never gets called.

To Reproduce
Run Code
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using Microsoft.SemanticKernel;
using Microsoft.SemanticKernel.ChatCompletion;
using Microsoft.SemanticKernel.Connectors.OpenAI;
using System.ComponentModel;

namespace AI_test
{
internal class Program
{
public class SuperHeroPlugin
{
[KernelFunction, Description("The best super hero")]
public string TheBestSuperHero() => "Ironman";
}

	static async Task Main(string[] args)
	{
		// Your PHI-3 model location 
		var modelPath = @"D:\AI Models\Phi-3\cpu_and_mobile\cpu-int4-rtn-block-32";

		// Load the model and services
		var builder = Kernel.CreateBuilder();
		builder.AddOnnxRuntimeGenAIChatCompletion("phi-3", modelPath);
		builder.Services.AddLogging(c => c.AddConsole().SetMinimumLevel(LogLevel.Trace));
		builder.Plugins.AddFromType<SuperHeroPlugin>();
		var kernel = builder.Build();

		// Create services such as chatCompletionService and embeddingGeneration
		var chatCompletionService = kernel.GetRequiredService<IChatCompletionService>();
		ChatHistory chat = new();
		OpenAIPromptExecutionSettings settings = new() { ToolCallBehavior = ToolCallBehavior.AutoInvokeKernelFunctions };

		// Start the conversation
		Console.Write("Who is the best superhero?");
		var question = "Who is the best superhero?";

		ChatMessageContent chatResult = await chatCompletionService.GetChatMessageContentAsync(question, settings, kernel);

		Console.Write($"\n>>> Result: {chatResult}\n\n> ");
	}
}

Expected behavior
returns "Ironman"
