VoidButChaotic Have you tried removing MCCC, or the entire Mods folder? If not, please do so now.
As for the "'use a new folder' trick," as you've called it, it only helps if you remove or rename the correct Sims 4 folder (i.e. the one the game is using), and if you don't put anything in the new folder, AND if you don't have OneDrive or another service that syncs your files and might restore the old Sims 4 folder before you get a chance to test. If you think one of these might be the reason trying a new folder didn't help, let me know.
