I'm unable to open Sims 3

Hello!! Just bought a new PC (Windows 11) and downloaded the EA app, Sims 3, and my packs. I don't have any mods or CC. When I get to the sims 3 game launcher and hit play, I'm re-routed to the EA app and am unable to start the game. I've spoken to three different customer support agents but to no avail, so I'm coming here as a last resort. 

Here's what I've tried so far (of which I remember): 
- Checked the .NEW framework

- Ran the game and EA app as an admin 

- Disabled onedrive

- verified game files

- uninstalled and reinstalled the EA app, base game, and packs

- "repaired" the game through the EA app

- cleared the game cache 

Is anyone else running into this problem and/or have any suggestions? Thanks in advance!

Warmly,

Jess
