Re: Sims 4 window freezing and minimizing, will not properly launch game.
@sunshinemeg97 Please 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, make sure Discord is closed—check the Task Manager's background processes list—as well.
If you get another crash, please move your entire Sims 4 folder out of Documents\Electronic Arts and onto your desktop. When you launch the game, if it launches, 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.
If that doesn't help either, please run a dxdiag and attach it to a post.
