Mising project subtype for creating Unit test project in VS

I am simply trying to create a Unit test project - .Net Framework And I get the error There is a missing project subtype. Subtype: '{3AC096D0-A1C2-E12C-1390-A8335801FDAB}'
is unsupported by this installation. What do I need to install to get this working please?

It should be simple right?
I went to install and re installed it, I am running Microsoft Visual Studio Enterprise 2019 Version 16.8.5

This used to work, but what "broke" it or how to fix it is beyond me.

    According to this Visual Studio bug report doing a repair on visual studio should fix it. I would recommend you update the project to use MSTest V2 when you a chance.
