@Zmias1 Uninstalling and reinstalling could help temporarily even if this is antivirus-related because an AV will often block a program the second time it's launched. It's also possible you wouldn't be able to reinstall the game at all, depending on the exact cause of the issue.
Norton is usually fine but occasionally does have issues with Sims 4. You can temporarily disable its protection and repair the game, as a test, but remember to reenable protection afterwards, and don't do anything else on your computer at the same time. Here's how:
