3.9.5.81版 downloadAttach下载图片时，文件为C:\wxhelper\WeChat Files\wxid_xxx\wxhelper(1)

[Yuanyuan1Xu]

手机给自己的微信号发一张图片，TcpServer()处理消息时downloadAttach下载该图片，msgId.dat图片文件本该生成在C:\wxhelper\WeChat Files\wxid_xxx\wxhelper\image下，结果保存在C:\wxhelper\WeChat Files\wxid_xxx\目录下，与文件夹wxhelper同名，变为C:\wxhelper\WeChat Files\wxid_xxx\wxhelper(1)。
找源码INT64 Manager::DoDownloadTask(UINT64 msg_id)
。。。。
if (!Utils::FindOrCreateDirectoryW(save_path.c_str())) {

return success;
.........................................................................................
INT64 type = *(INT64 *)(chat_msg + 0x38);
type = default 使得文件名为wxhelper目录名，

但是这不知道是什么原因引起的，如何解决？
