can't be loaded because another AssetBundle with the same files is already loaded. error while loading different bundles

Question

I've tried load asset bundles from URLs. When I load only single asset bundle, it works well. But if I try to load multiple asset bundles, Unity gives this error: The AssetBundle 'https://example.com/uc?export=download&id=1234567' can't be loaded because another AssetBundle with the same files is already loaded.

example code as follows

using System.Collections;
using UnityEngine;
using UnityEngine.Networking;
using UnityEngine.SceneManagement;
using TMPro;

public class sahnecagir : MonoBehaviour
{
    public TextMeshProUGUI Log;

    // Start is called before the first frame update
    void Start()
    {
        StartCoroutine(LoadBundleFromUrl("https://example.com/uc?export=download&id=123456", 2, 0, (uint)Crc.Gifts));
    }

    IEnumerator LoadBundleFromUrl(string url, int tip, uint version, uint crc)
    {
        using (UnityWebRequest uwr = UnityWebRequestAssetBundle.GetAssetBundle(url, version, crc))
        {
            uwr.SendWebRequest();

            while (!uwr.isDone)
            {
                if(tip == 1) Log.text = "Rooms loading " + (uwr.downloadProgress * 100).ToString("0")  + "%";
                else if(tip == 2) Log.text = "Gifts loading " + (uwr.downloadProgress * 100).ToString("0")  + "%";
               
                yield return null;
            }

            if (uwr.isNetworkError || uwr.isHttpError)
            {
                Debug.Log(uwr.error);
            }
            else
            {
                if (tip == 1)
                {
                    MainConfig.Instance.RoomBgBundle = DownloadHandlerAssetBundle.GetContent(uwr);
                }
                else if (tip == 2)
                {
                    MainConfig.Instance.GiftBundle = DownloadHandlerAssetBundle.GetContent(uwr);
                }
            }

           

            if (uwr.isDone && tip == 1)
            {
                Log.text = "Rooms loading 100%";
                StartCoroutine(LoadBundleFromUrl("https://example.com/uc?export=download&id=1234567", 2, 0, 0));
            }
            else
            {
                Log.text = "Gifts loading 100%";
            }
            yield return null;
        }
    }
}

In my case I've been trying to modify a bundle with different files but Unity refuses to load the two different files even if they have different names, a different structure, different files inside, nothing.

Opening the bundle in Notepad++ brings up what I assume to be a "container name" of CAB-a317cdbf067bab183d6dd12d870c1407 as an example. This is what Unity seems to be checking for to determine whether a bundle is "identical."

A simple find and replace to a different name and boom. The bundles load now.
