Sims 4 gets stuck on loading screen but only in one specific save

So I have had this problem for a bit now and it only happens on my 100 baby challenge save file. I can load the file and it succesfully takes me to the world map but when I click to get into the household, it always freezes to the loading screen. I don’t use script mods on this save file but use cc, but it doesnt happen on other save files. Please help!
