The problem here is that this mod can't start up properly if Nauvis is the only planet. I don't consider this a problem worth fixing because this mod is completely useless if Nauvis is the only planet. However, in this case, the other planets are still there and intended to be used; Hide Space Age Spoilers has just hidden them. There isn't anything I can automatically do about that, because other mods create hidden planets for various internal reasons that should not be on the list of destinations.

My suggestion is, since Hide Space Age Spoilers requires that you manually reveal content, you disable this mod until you've discovered and enabled at least one other planet. This mod is (to the best of my knowledge) quite safe to add to a game in progress so there's no problem in doing that.
