XUnit Tests ARE Discovered, WILL Run In All Tests, but do NOT Run In Playlist

I have a weird problem where in in VS2017 v15.6.6 my Xunit tests have been running fine all morning in both "All Tests" and a separate individual playlist.

After adding "xunit.methodDisplay" to my app.config in the test project the tests in that playlist will ONLY run in the "All Tests" list. If I try to run them in the playlist view, I get this error

System.IO.FileNotFoundException: MSTest.TestAdapter.1.1.17/build/_common/ Microsoft.VisualStudio.TestPlatform.MSTest.TestAdapter.dll at Microsoft.VisualStudio.TestWindow.Controller.TestPlatformProvider.PerformShadowCopy(IEnumerable`1 testExtensions

My solution targets .NET Framework 4.6.1. All my versions seem to match, I have found (and verified my info matches solutions for) several questions about tests not being discovered at all or not being run in All Tests.

Eventually the "Not discoverable" questions led me back to Xunit's "Getting Started" page, which has a section all about running in VS, including this handy little gem:

Deleting this folder solved my problem.
