Trying to download the windows build immediately blocks it for me. Both Chrome and Windows Defender detect and block it.

False positive, not sure of anything in there that would raise a flag, though.

Same. Can't download. Will try firefox

This is a known issue of Windows Defender. Unfortunately Godot nor any game developers can do anything about it, because it's Microsoft's fault. I found this github discussion thread about the same false positive.
