Saves deleting itself

So i’ve been playing on the xbox one for six years now and this is the first time i’ve had the issue of my save deleting itself. While I was playing, I was switching households in manage worlds and when I got into my household I tried to save the game but it gave me an error saying that It couldn’t save. So since i had already saved before I switched households, I decided to restart the game to see if that would fix the problem but it completely deleted the entire save folder. Not really sure what to do right now and i’m a bit frustrated because I’ve worked in the save folder for a long time and I can’t recover it. If someone could help me out that’d be amazing please!
