Everything is Gone…?

So I moved my sims 4 folder to my desktop to try to fix the reapers rewards, which it did for like a second then it went back to me not getting any tasks. So today I tried to play and everything is gone. I had already started a new game and the family I started is gone. Then I tried to switch the folders and put the new one on my desktop and put the old one back in the folder but all of it was gone…. But there was also an extra file? So I have two sims 4 folders and one sims 5 folder which I have no idea how that even happened. I feel so discouraged. I spent so much time on this game 😖 I don’t know what to doooo
