Hello, can you share what did you used for extracting it?
Everything is okay after we test it with winrar and 7zip just a few minutes ago by redownloading the file here.

It was not extraction. Windows 11 File Explorer refuses any interaction with the zip file. It won't let me open it. Now, I did right click and "Open With - Winrar" and extract the files no problem, so this would seem to not be a big issue, but I do find it rather weird the Windows File Explore just does not like this zip file in particular.
