Re: my game after update wont open

@elliewantplay  Please disable Origin in-game: hover over your username, select Application Settings, then the Origin in-game header, and disable the option at the top.

If you have Discord installed, please also check the Task Manager's background processes list for any Discord-related entries, and shut them down if you find them.

If that doesn't help, please move your 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 it yet; just see whether you can get far enough to start a new save and play in live mode for a bit.  Let me know either way.

If you get the same white screen, please run a dxdiag and attach it to a post.
