I would not normally expect that these launchers are "Jealous" in some way and are saying to themselves - "You are playing way to much of that other game, and not me, so I'll randomly clobber that nice game you've been playing...." anyway. That's the conspiratist [or is that Conspiratorialist?] in me I guess. But what with all the other "Real" conspiracies going around: Why not?

But after shutting that GoG thing down, I have played all day hard - gathering Moogle Tomes - and no FFXIV client crashes. So that's a data point. And it lines up with a previous comment that a LoL [League of Legends I presume] Launcher was causing problems for someone.

Say. Do these Launchers look for programs that are "adding features" [not using the Exp banned word here] games, and deciding that other games are baddies and clobbering them? Naw. That's second order conspiracy theory, certainly. But we do have two data points on that line.
It is more likely the other launchers use different versions of DirectX or ActiveX (yes, most launchers are Internet Explorer based) during their idle stages to load the banners, links, pre-launch, and media.
While your video card is happy to be running a DirectX11 game, it doesn't like to be interrupted to also run other DirectX versions or media-overlays at the same time, even those that are in another window in the background or minimized.

Less stuff running in the background = better for gaming

So exit/shut-off/do-not-run-on-Windows-startup all your launchers and only start the one up for the game you are going to play.
