Can't load a household or save

hi. idrk how to ask questions on here/ask for help but im gonna try. i play the sims 4 on a macbook air and recently my sims game is unable to load a certain household. the rest of the households are fine to load into except this one. (ive tried literally everything you can think of to fix it.) when i do try to load into the one household/lot it just loads infinitely. i cannot enter live  mode with this family. i play with Mods and CC as well. i've added the whole family to another household using MC Command Center and they don't appear. like they're there, but they're invisible and won't show up but i can still play as them and have them interact with things just no visible sim can interact with them (because they're invisible). i can't save the game either because it also just loads infinitely. i have repaired, unistalled/reinstalled, reset my game, cleared the cache, done basically anything i can think of. im hoping my save isn't just broken cause that would suck.
