Error: The 'MSBuild:UpdateDesignTimeXaml' code generator crashed: Not connected

This issue has been moved from a ticket on Developer Community.

When I delete the bin/obj of the project and start the project the restore packages hangs and a lot these errors appear. I do have to force quit VisualStudio code and do this a few times.

This happend for a while, I am now up to date with the version.

This happend also with your sample flyout project.
