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.
