Content Missing from Creative Library

I was playing sims 4 on my ps5 last night and I was just placing townies when out of the blue the game crashed and it showed a message saying an error happened. When I load back in my ENTIRE library was gone. I've never been so heartbroken the only way to get it back was to get ps plus and save it to the cloud. I did get it today but the damage was done that most recent file is completely gone. I just wanted to rant because I was literally prepping a whole new world I was looking forward too and it's just nonexistent. If you do have any tips or solutions it'd be very appreciated.
