Sims 4 Stuck on Loading Screen

Well hey, try moving your Tray, Saves, Mods, and optionally your screenshots to your desktop. Then delete the sims 4 folder completely, start a new game and let it regenerate everything. Redo your custom controls and maybe adjust your sim limit then close and save and move all your Tray, Saves, and Mods back in and see what happens. It worked for me and I think once they did the update, the files got corrupted and mixed up a bit so even if you didn't get the EP you might have still gotten messed around.
