There is a major issue being experienced across the VS2019 community when updating VS2019 to the latest 16.6.0 version. See https://developercommunity.visualstu...omment-1041312 (and also https://developercommunity.visualstu...up.WMIProvider for all the duplicate reported problems!).

I had the issue myself, and for me Retry and Modify then a reboot seemed to fix it.

Just a heads up that you might wish to delay updating to 16.6 until this issue is resolved.
