Disable plugins outside of editor?

By “regenerate” I take that to mean run GenerateProjectFiles.bat again to build a new UE4.sln, yes? I did that, but when I open and Build, it seems the previous build is still being seen, as it only took seconds to build and usually it’s around 45 minutes. And when I then Debug new instance, I get the same two messages as before, Project being out of date and not being able to find the OculusAudio plugin. Where might I be going off map?

Thanks.
