[CC RELATED] Error Code 102:20ece5dd

So I just recently got the sims 4 on pc after playing on ps4 for years and I bought The university pack and the tiny house living and I've been redoing the whole university map I've been working very hard on it. I had only one room left to finish and went to open my game yesterday and this popped up "error code 103 20ece5dd6adbe682 we recommend you relaunch your game" It was instantly after I updated origin and I thought it was that. I repaired my game twice and even deleted and reinstalled it but nothing worked. So I went to google and googled the error code but couldn't find anything. I was looking though my files and deleted some mods so I could get the updated version but it didn't work. So I just tried copying all of my mods folder and taking it out of my game. But it deleted instead. yeah, I know i'm basically a noob and didn't know anything about how updates can just fry your game altogether. I opened my game and it worked but the whole university that I had been working so hard on for a week is all empty. Can someone help? I really don't know what to do?
