Ok so by blind luck I uninstalled .NET Core 3.0 runtime/SDK, and attempted to create an older project (WPF using .NET Framework 4.7.2) and saw this error come up

Cannot open any project in Visual Studio 2019: The tools version "15.0" is unrecognized

Which allowed me to google, and lead me to this page https://developercommunity.visualstudio.com/content/problem/515088/cannot-open-any-project-in-visual-studio-2019-the.html

Which in turn had this information on in

This happens because you have older versions of msbuild assemblies in the GAC which gets loaded when trying to use a newer version of VS (2019). We don’t support this mixed mode development.

Run the following commands from an elevated Visual Studio Developer Command prompt:

gacutil /u “MSBuild, Version=15.1.0.0”
gacutil /u “Microsoft.Build.Conversion.Core, Version=15.1.0.0”
gacutil /u “Microsoft.Build, Version=15.1.0.0”
gacutil /u “Microsoft.Build.Engine, Version=15.1.0.0”
gacutil /u “Microsoft.Build.Tasks.Core, Version=15.1.0.0”
gacutil /u “Microsoft.Build.Utilities.Core, Version=15.1.0.0”
gacutil /u “Microsoft.Build.Framework, Version=15.1.0.0”

After I did that, I was able to reinstall .NET Core 3.0 runtime/SDK and all was ok
