Sims 4 game will NOT launch

@Wmasumbe  Do you use a third-party antivirus?  If so, please disable it, temporarily of course, clear the EA App's cache:

and repair the game: open the App game library, click Sims 4, and select Manage > Repair.  Then try to play, with the antivirus still disabled.  As long as you don't do anything else at the same time, your computer should be safe.  If this helps, set exceptions for TS4_x64, TS4_DX9_x64, and TS4_Launcher_x64, or the Bin folder they're in.

If you don't use a third-party antivirus, I'd still clear the App's cache and repair.  If you've installed through Steam, you'll need to repair through Steam instead; the option is called "Verify the integrity of the game files" or similar.

If this 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.  You'll be able to (try to) launch Sims 4 without reinstalling anything.
