Microsoft didn’t release a new Windows 10 insider build last week due to a bug that prevented UWPs from opening as per a tweet by Dona Sarkar. So, the latest build released for the Fast ring is still the Build 17046.
#WindowsInsiders we’ve hit a bug that prevents UWPs from opening so we will not be flighting a new build today. Have a great weekend! ❤️

But Dona’s latest tweet has raised hopes for a new build this week. A new build may come not before Wednesday however.
#WindowsInsiders we have a build in mind. You know what that means. Canary, selfhost the next 2 days & if all goes well, W or Th release.
