Re: WHITE SCREEN ON WORLD MAP
@Maik4467 Please repair the game in Origin: open your game library, right-click on the Sims 4 icon, and select Repair.
If that doesn't help, please move your entire Sims 4 user data 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 this folder yet; just see whether you can start a new save and play for a bit. Let me know either way.
If you still get the white screen even in the clean folder, please run a dxdiag and attach it to a post.
