Nothing is saving, game unplayable

I play the Sims 4 on xbox and recently i haven’t been able to save anything to my save files, it keeps saying error 34 then when i go to the main menu the whole family is gone. This keeps happening with multiple save slots/households, it makes the game unplayable. I have tried restarting my xbox multiple times, clearing the cache, basically doing everything google said to do but nothing is fixing this. I would appreciate if EA could fix this issue immediately because there is no reason this should be happening. I don’t download mods or anything, and I always properly turn the game off so I don’t know why this issue is happening and there is nothing that can be done to prevent this from what I know. These households I have took many months of work and much money spent on the game but if I can’t save any of the work I do, there is no point in playing the game anymore. EA, please fix this.
