With Edge 188.8.131.52 I navigated to https://visualvm.github.io to download 1.4.3 and it will show scanning in the downloads, but never finish. I hadn't tried with previous versions.
When I close Edge browser and cancel download, the Edge process remains with children and cannot be launched again until the process is killed.
@giblet70, I have reached out to our Smart Screen team to see what is going on here. I am able to reproduce this issue. Thank you for bringing our attention to this issue. Elliot
