无法加载，因为已加载另一个具有相同文件的 AssetBundle。加载不同捆绑包时出错

问：

我试过从 URL 加载资产包。当我只加载单个资产包时，它运行良好。但是，如果我尝试加载多个资源包，Unity 会给出以下错误：The AssetBundle 'https://example.com/uc?export=download&id=1234567' can't be loaded because another AssetBundle with the same files is already loaded.

示例代码如下

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;
        }
    }
}
