This happened to me Saturday night on the PS4 (8/16/20). I even posted about it but not single soul has helped me.
absolutely do not save the game when this happens!
If you’re on PlayStation what you’ll want to do is go to the game. Don’t click on it to load hit options. Upload/Download Saved Data
find the most recent “My Library” save and download it to the system. (Do not download anything else and make sure the My Library save is not when the crash happened or you will lose everything)
the save must be prior to the crash
I cannot tell you how to do this on Xbox but I imagine it is similar to PlayStation or every computer as you need to redownload the my library file.
Make sure you are saving often and uploading to storage (ps4) if you’re on Console
I have found that this happens when I download things to my gallery that I don’t realize is cc. My whole game crashes. Hope this helps!
I had this issue occur for me this morning.
For the past few days, occasionally when I tried to download things from the gallery I would receive an error message stating that My Library was full. Last night I got this message while trying to save a lot. Each time I deleted a few of the preinstalled Maxis library items, and sometimes the download/save lot would then work, sometimes not.
Upon fire up the game this morning, I got an error message saying corrupt data and my data would be deleted.
Let me know if you need additional information.
Is there a way to restore the data?

@Mr2timescorer I've merged your post into the current bug report for this issue. Please click the "Me Too" button at the bottom of the first post on the first page of the thread.
If you have a backup of your library on USB or in the cloud, you can restore your missing content that way.
