Product Group removal for featured wine kills homepage?

I have what I think is a weird one, but perhaps I’m confused about something. We were attempting to remove the “featured wine” content block from our home page - doing so caused the homepage to load the .com/error page, but the “Return to homepage” button on the bottom of the error page takes you to the correct edited homepage. Not sure how that happened or how to solve the problem. Thoughts?

Edit: Problem has been solved.

How did you solve this?
