*Submitted zip to MS analysis, lets see what happens.

ok, got results (from the current prerelease build:

The warning you experienced indicates that the application had not established reputation with the Microsoft Defender SmartScreen Application Reputation feature at that time. We can confirm that the application (SHA256:64F4D28CC32D388890E39EF44C49C2B43BC889097B55BA0068432AB43EAAB9E7)" has since established reputation and attempting to download or run the application should no longer show any warnings.

Please note, however, that the submitted files are not signed using a valid digital certificate. Unsigned files will have to establish reputation each time a new version is released.
