Steamworks.NET Callbacks Not Triggering for Achievements

Hello everyone,

Unity 2020.3.4f1
Steamworks.NET (20.2.0)

I'm currently facing an issue with Steamworks.NET integration in my Unity project. The problem is that the callbacks for Steam APIs, specifically related to achievements, are not being triggered. Below, I'll outline the steps I've taken and the observations I've made:

Steps Taken:

I used the Package Manager to add Steamworks.NET to my Unity project.
I added the "SteamManager.cs" file to the project to handle Steam initialization.
I created a new script called "AchievementController" to manage achievements.

Observations:

The SteamManager seems to be running as expected, and its update method calls "SteamAPI.RunCallbacks();" properly.
I have double-checked the App ID for my game using a CGameID object, and it is correct.
My game has several achievements defined on the Steamworks developer portal, and they are marked as "PUBLISHED."
I verified that the callbacks for achievements (e.g., "UserStatsReceived_t") are being created.
The method "SteamUserStats.RequestCurrentStats()" returns TRUE, indicating that the stats are being requested from Steam.
My Steam application is OPEN and shows "RUNNING" next to my game in the Steam client.

To troubleshoot the issue, I even modified the SteamManager script to trigger an event when initialized, thinking it might be a race condition. However, this approach didn't yield any success. I also tried disabling and destroying the SteamManager to eliminate potential conflicts, but the callbacks still aren't being called.

Below are the entirety of my relevant scripts:

AchievementController.cs

using System;
using Steamworks;
using UnityEngine;

namespace CrossBlitz.Steam
{
    public class AchievementController : MonoBehaviour
    {
        protected bool m_initialized;
        protected CGameID m_gameId;
        protected Callback<UserStatsReceived_t> m_userStatsReceived;

        protected bool m_requestedStats;
        protected bool m_statsAreValid;

        private void Awake()
        {
            SteamManager.OnSteamInitialized += OnSteamInitialized;
        }

        private void OnDestroy()
        {
            SteamManager.OnSteamInitialized -= OnSteamInitialized;
        }

        private void OnSteamInitialized()
        {
            if (!SteamManager.Initialized)
            {
                Debug.LogError("Steam manager not initialized.");
                return;
            }

            // Cache the GameID for use in the Callbacks
            m_gameId = new CGameID(SteamUtils.GetAppID());
            Debug.LogError($"GameId = {m_gameId.m_GameID}");
            m_userStatsReceived = Callback<UserStatsReceived_t>.Create(OnUserStatsReceived);
            m_initialized = true;

            string username = SteamFriends.GetPersonaName();
            Debug.LogError($"Name = {username}");
            //SteamFriends.ActivateGameOverlay( "Stats" );

            Debug.Log("Created the requested stats callback.");
        }

        private void Update()
        {
            if (!SteamManager.Initialized)
            {
                Debug.LogError("Steam manager not initialized.");
                return;
            }

            if (!m_initialized)
            {
                return;
            }

            //Debug.LogError($"m_userStatsReceived = {m_userStatsReceived != null}");

            if (!m_requestedStats && Input.GetKeyDown(KeyCode.A))
            {
                var success = SteamUserStats.RequestCurrentStats();
                //m_requestedStats = success;
                Debug.Log($"Requested Stats: {success}");
                // var achievementName = "ACH_MASTER_MELDER";
                // if (SteamUserStats.GetAchievement(achievementName, out bool achieved))
                // {
                //     Debug.Log($"Achievement {achievementName} success! Achieved? {achieved}");
                // }
                // else
                // {
                //     Debug.LogError($"Could not get {achievementName} did you publish changes?");
                // }
            }
        }

        private void OnUserStatsReceived(UserStatsReceived_t pCallback)
        {
            Debug.LogError($"Requested stats?? {pCallback.m_eResult}");

            if ((ulong)m_gameId != pCallback.m_nGameID)
            {
                Debug.LogError($"Received stats from {pCallback.m_nGameID}, ignoring.");
                return;
            }

            if (EResult.k_EResultOK != pCallback.m_eResult)
            {
                Debug.LogError($"Error receiving achievements {pCallback.m_eResult}, you should handle this.");
                return;
            }

            var achievementName = "ACH_MASTER_MELDER";

            if (SteamUserStats.GetAchievement(achievementName, out bool achieved))
            {
