Did you remove something that doesn't belong to the mod? Have you tried reverifying your game files?

I'm not sure how you do it manually, but using Vortex, I was able to easily disable the mod when I was on the test branch. I did lose some stuff in my expanded chests, but other than that the save was fine. So V+ shouldn't be screwing up your save files that badly. (Although it could depend on which options you had turned on. But I'm not sure which ones would be so bad that you couldn't get it started.)
