@Ggman if you have a premium, you can build BAS from source and make sure that there are no viruses and cannot be. Also, if you downloaded the program from official servers, I think there is no reason to worry. As a result, it looks more like a false positive from the defender, I checked the files several times on different versions - in my case, no threats were found. You can also upload this file to VirusTotal and check it out.
In case everything is fine, I would recommend sending a report to microsoft about a false positive so that the defender does not delete this file, or add it to an exception.
