BellaandMaxandMe This error has become so generic that it's not helpful anymore. A bad mod is the most common cause, but there are plenty of others. So far, I've seen these:
- bad mods or custom content
- antivirus blocking the game
- OneDrive getting in the way
- an old graphics driver
- other undetermined issues with the user account, solved with a new Windows account
I also have one report that disabling Game Mode and Game Bar helped. For other games, a Windows beta build is one cause, although I don't know whether it's affected Sims 4. Point is, I always start with mods because that's the single most likely culprit and because it's easy to test without them. But if that doesn't help, I look for other causes.
chillyw316 If you want to contact EA customer support, the link is at the bottom of the page. But I don't think it's an account issue, and EA support is not computer support, so there's only so much they can do.
