Unplayable after update Xbox

Before the update in build mode I could build a house for a few hours before it crashed but now I can't even place an item without it crashing in build mode. If I go to the gallery I have to restart my game as it still gets stuck and I haven't used cheats in this save file either.

I only have 2 Sims in my household and a horse.

My horse it glitchy they need to fix that pack the ball is still glitchy I have to delete it and place a new one for my horse to play but can't access build mode.

My child sim when going to school gets to the street then stops and when I click on them to go to school or after school activities they just stand there I have to travel with another SIM to get them to school.

It won't progress any career or after school activities I have the bar full and the tick but no-one gets promoted.

Also on build mode when I can use it for a few seconds all the build and buy items all come up as if they are new and they aren't.
