Do you have any LastException files in Documents\Electronic Arts\The Sims 4 ?
Best is to delete the ones you have, then trigger the error and check if new ones are created.
If that is the case, please upload them to a new post in this thread.
Please either create a .rar file to upload or copy/paste the content into your post.
Deleting the file won't fix your issue. Uploading the file is meant for troubleshooting.
Unfortunately I most recently got Error Code: 800
As I understand it, that means my entire save is corrupted?
