Taniya2017 Just in case it's the issue, please disable TotalAV temporarily. You don't need to uninstall it; the point is to have it not working for the moment. Once you've done that, clear the EA App's cache:

Repair the game (EA App > Sims 4 > Manage > Repair), and try again to play. If that works, reenable TotalAV and set exceptions for TS4_x64.exe, TS4_Launcher_x64.exe, and EADesktop.exe.
If that doesn't help, 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. (Just keep declining until you're asked some security questions instead.) You'll be able to at least try to launch the game without reinstalling anything.
the first part didnt work..
