Hi! That sucks! Though I'd like to chime in with the hopes of helping, at least until Raze races along with better ideas. Or until all ideas are razed down.
Sorry, done with the puns now.
I faintly recall someone mentioned at some point that deleting older saved helped them with loading times for some reason. You could try this just for the hell of it.
As with any potentially destructive attempts, do a backup first. So navigate to C:\Users\sound\Documents\Larian Studios\Divinity Original Sin 2\PlayerProfiles\YourPlayerProfile\Savegames\Story and move all folders except say... The two most recent ones, to someplace else.
I assume you're not using mods?
