@Meza_Origin If OneDrive is running on this computer, whether you use it or not, please try pausing syncing before you play. Right-click the cloud icon in the lower-right corner of the screen to see the option.
If that doesn't help, please move the entire Sims 4 folder out of Documents > Electronic Arts and onto your desktop. When you launch the game, if it launches, a clean folder will spawn with no content. (Your saves and other content will be intact in the folder you moved but temporarily not read by the game.) Don't add anything to the new folder yet; just let me know whether you can get far enough to start a new save and play in live mode for a bit.
If that doesn't help either, please let me know what antivirus you use.
@Meza_Origin Even if McAfee is probably not interfering, please uninstall it using the company's own removal tool:

You don't need to activate it if you're never going to use it. Restart your computer after uninstalling and before trying to play.
If that doesn't help, please create a new admin Windows account and try playing in that. Make it local, as in, don't link it with your Microsoft account. You'll be able to (try to) launch Sims 4 without reinstalling anything, but your saves and other user content won't be available. That can be addressed later; for now, just let me know whether the game launches at all.
