KittenElla100 As a test, please try playing in a clean user folder. Move the entire Sims 4 folder out of Documents > Electronic Arts and onto your desktop. When you launch the game, a clean folder will spawn with no content. Don't add anything to the new folder yet; just start a new save and see how it runs, that is if you can get that far.
If that doesn't help, please put the EA App in offline mode, then take your computer offline before trying to play. Let me know whether that makes a difference.
I already tried a clean folder and trying to open in offline mode doesn't change anything, it just flashes/glitches white and black for a few seconds then crashes
