Another potential cause is you installed a .NET Core version which is incompatible with Visual Studio. This might be unrelated to the original question by the OP, since it concerns different version numbers, but since I landed on this page while looking for help I thought this might be useful to others.

At the time of writing, I installed .NET Core 2.2.203 which is not compatible with Visual Studio 2017 (Professional 15.9.11).

The .NET Core download page lists a separate download for Visual Studio 2017. Be sure to download this one when you intend to use Visual Studio 2017. The current supported version is .NET Core 2.2.106.
