My game closes down in build mode

hcldh59xgf5e  Some lots have the OtG challenge by default, but probably not museums.

Please go into Documents > Electronic Arts > The Sims 4 and delete any lastexception files you see there.  (This is important—get rid of older files that may contain stale data.)  Load the game, try to load one of these lots, still with your Mods folder removed, and see whether you get another LE.  If you do, please attach it to a reply here.  It's fine as a .txt file, but you'll probably need to delete its first line.
