Error permissions when moving directory

I have tried to solve this error for some time but I can not find the solution.

Code

public static void PermDirectory(string perms)
{
     var directory = new DirectoryInfo(perms){ Attributes = FileAttributes.Normal };
     foreach (var info in directory.GetFileSystemInfos("*", SearchOption.AllDirectories))
     {
         info.Attributes = FileAttributes.Normal;
     }
}

public static void DeleteDirectory(string path)
{
     var directory = new DirectoryInfo(path) { Attributes = FileAttributes.Normal };
     foreach (var info in directory.GetFileSystemInfos("*", SearchOption.AllDirectories))
     {
        info.Attributes = FileAttributes.Normal;
     }
     directory.Delete(true);
}

....

if (Directory.Exists(dir_instancias_temp))
{
      DeleteDirectory(dir_instancias_temp);
}
string perms = dir_instancias_skyblock;
PermDirectory(perms);
Directory.Move(dir_instancias_skyblock, dir_instancias_temp);
string path = dir_instancias_temp;
DeleteDirectory(path);

Error
