It should not be related to Chinese OS, as already pointed out. You may want to try the latest v2025.12 first.
Also make sure the folder D:\phpstudy_pro\WWW\test.peixunxueyuan\uploads exists and you have granted write permission to that folder.
Note also that there is an “unauthorized” error in your screenshot. As suggested, you should check HTTP response either in the Debug bar or in the browser’s Network panel. See the content of HTTP response to find the error.
If it still does not work and you are a registered user, you better send the the required info to support for testing directly.
