解决办法:打开UMPPostBuilds.cs脚本修改 public static void BuildWindowsPlayer64(string path, UMPSettings settings)这个方法

 public static void BuildWindowsPlayer64(string path, UMPSettings settings)
    {
        string buildPath = Path.GetDirectoryName(path);
        string dataPath = buildPath + "/" + Path.GetFileNameWithoutExtension(path) + "_Data";
 
        if (!string.IsNullOrEmpty(buildPath))
        {
            if (!settings.UseExternalLibs)
            {
                CopyPlugins(settings.AssetPath + "/Plugins/Win/x86_64/plugins/", dataPath + "/Plugins/plugins/");
                string[] files = Directory.GetFiles(dataPath + "/Plugins/x86_64/");
                foreach (string str in files)
                {
                    string file = Path.GetFileName(str);
                    Debug.LogError(file);
                    File.Copy(str, dataPath + "/Plugins/" + file);
                }
                Directory.Delete(dataPath + "/Plugins/x86_64/", true);
            }
            else
            {
                if (File.Exists(dataPath + "/Plugins/" + UMPSettings.LIB_VLC_NAME + ".dll"))
                    File.Delete(dataPath + "/Plugins/" + UMPSettings.LIB_VLC_NAME + ".dll");
 
                if (File.Exists(dataPath + "/Plugins/" + UMPSettings.LIB_VLC_CORE_NAME + ".dll"))
                    File.Delete(dataPath + "/Plugins/" + UMPSettings.LIB_VLC_CORE_NAME + ".dll");
            }
        }
        Debug.Log("Standalone Windows (x86_x64) build is completed: " + path);
    }
