livyprogamerlolx I apologize for the late reply. I'm not sure whether your post was moved to this forum after the fact or I just missed it.
Either way, please create a new admin Windows account and try playing there. Make it local, as in, don't link it to your Microsoft account or any email address. You'll be able to (try to) launch Sims 4 without reinstalling anything, but your saves and other user data won't be available.
If this doesn't work, let me know what antivirus you use. If it does work, but you want to fix the game in your main Windows account, let me know whether OneDrive is running when you're signed into that account.
