We have received and investigated a few reports of builds failing that utilize the most recent windows-server-2019-vs2019:stable image that was released on Thursday May 21, 2020.
Errors are related to Visual Studio license is expired and SSH is unavailable to investigate further.
We are currently working to resolve these issues and produce a new image, however, we can not provide an exact ETA for deployment of the next image.
Once the new stable Windows image is available we will update this announcement, accordingly.
