Sims 4 Crashing On Plum Bob Loading Screen

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

If that doesn't help, pleaese 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 start a new save and play for a bit.  Let me know either way.

If you can't play even in a clean folder, please run a dxdiag and attach it to a post.
