Re: Game crashes in Live Mode after update

@RedEnigmaFilms  The fact that a new save works fine suggests that the problem is the old save, not your computer or the game overall.  Please try playing a backup version of your existing save, still with no mods.  Use the manual method of recovering backup saves here:

Copy over the backups rather than just moving them, as you did with the main save, so the original backups will also remain intact.

If this doesn't help, please try loading a different household within your main save, preferably one in a different world, and let me know whether it helps.
