Re: The Sims 4 won't load past main menu
@shotofanxiety 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, and when you launch the game, a clean folder will spawn with no content. (Your saves and other content will be intact in the folder you moved but temporarily not read by the game.) Don't add anything to the new folder yet; just let me know whether you can get far enough to start a new save and play in live mode for a bit.
If that works, restart your computer and try again.
If that doesn't make a difference, please let me know what antivirus you use and whether OneDrive is running on this computer. Please also run a dxdiag and attach it to a post.
