If so, did you in fact create a new admin Windows account, a local one (not tied to a Microsoft account or any email address), and try to play there? Did you try temporarily disabling your antivirus at the same time? That's not a good idea in general, but it's safe enough if you're only trying to open Sims 4 and reenable the AV immediately afterwards.
Omw I didn't switch off the antivirus I just allowed it through the CFA (controlled folder access) I was too scared to switch it off tysm it worked I did make a new windows account and it didn't work but I think the AV was stopping it I'm so thankful rn
