I'm getting the same when trying to download on a machine that has real-time protection enabled in windows defender. Turns out it's a known and very common false positive to a trojan script.
To download, temporarily disable "real-time protection" in "windows virus & threat protection settings". To be 100% sure the executable is safe, unpack the zip and scan the exe file manually with an antivirus of your choice.
It's annoying but it is what it is.
I did pack the zip file with 7-zip which is listed as one of possible causes of this false positive. The next update will be packed with some other zipper just to exclude this as a possible cause.
