Got a strange error after creating a new C# application

[Doctor-Who]

I created a new C# console app. Nothing fancy. I hadn't even added anything to it yet, such a NuGet package. Then I compiled it, but it failed with lots of errors. e.g.: Unexpected system error mode before loading a package.



VS 2017 gave me a link to the ActivityLog.xml file. Once I passed all of those errors I finally got to what I think might be the real problem. Here's the error it gave:

Why would VS 2017 have such a huge hiccup on a brand new C# console app?
