I think the A0.43.zip download file might be corrupted. The other files open up just fine, but this one specifically will not open with a Windows "Compressed File is invalid" error popping up.

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.
