Crashing

Half the time when I am saving my game it kicks me out of the game and doesn't save. The other half it just kicks me out randomly.  It doesn't send me to the load screen it completely shuts down . Also it won't let me save lots to the gallery. Build mode is lagging, when I try to sell things from my household it takes at least a full minute  for it to sell  and if I press the button to allow me to sell all of an item in one shot the game freezes. I have an xbox one so I have no mods or cc. I have tried uninstalling everything and reinstalling as well  as turning off console and unplugging.  They didn't help  and the problem persists.
