Unreal Engine takes too long to load Visual Studio

Hi. I have been getting this cmds pop up recently when I am creating a C++ Project and when I am creating a new class. I was puzzled, but didn’t pay too much attention to it. But then I realized my visual studio files takes much, much longer to generate, or just doesn’t at all. I opened up my old projects and they all work fine, with no popups whatsoever. Any idea what this is? Much appreciated.

Nevermind. I figured out the problem. Apparently I had visual studio 2017 set up. Still strange as I don’t remember changing my defaults.
