I'd disabled Alternate Start (plus the two compatibility mods) since I'd read that it may have been the cause, but that didn't fix it so I re-enabled them. LOOT complains about the following in regards to Update and the 3 DLCs:

SSEEdit v4.0.2 found ## ITM records, ## deleted references and ## deleted navmeshes. (Rest Omitted)

Not sure if that's relevant, but there's that. I'm going to bed now or I'd continue the trial and error of disabling each individual mod to see what the problem child is. It launches fine with no mods enabled in Vortex (it's replaced NMM, for those not in the loop), and I'd removed all of the mods in-game when I'd disabled all of the Vortex mods and got the game to launch (some things still hang out in my library in the mods menu, but I can't delete them so...).

Figured I'd post here to see if you all could save me some hassle tomorrow. Thanks in advance!

Figured it out... First was the Dwemer mod. Someone else also had the problem but the mod author didn't so it was unresolved. Then, my version of RaceMenu was apparently for normal Skyrim. A quick fix, that.
