Another possible cause could be an incomplete or corrupted download. Sometimes browser extensions, antivirus software, or other security tools can interfere with downloaded files.
I know other users have successfully downloaded and extracted the files, so it might just be a bad download this time.
Could you try the following?
Try opening the file with 7-Zip (Windows' built-in extractor can sometimes have issues with certain ZIP files).
Download the file again and see if the issue persists.
Check if you have any program or browser extension that could be blocking or modifying the file.
Sorry for the trouble, and let me know if the issue persists.
