@sw33tpinkbabi It's not a reported issue, as far as I've seen, but that doesn't mean you're the only one affected. If you'd like to post this as DX11-related feedback, please do so here:

EA is actively monitoring that thread, so someone should see your post whether you get a direct reply or not.
Aside from a dxdiag, I'd suggest posting any current (post-DDU) error you see in the Reliability Monitor that you can confirm happened when you were running Sims 4. Hit Windows key-R and enter "perfmon /rel" without quotes, and you'll see a chart of errors and updates with a column for each day. Today is on the right. You can right-click an error name (at the bottom of the screen) and select "View technical details" to get more information. Everything is timestamped, although be sure to double-check the time in the technical details in case the one on the chart is incorrect, as happens sometimes.
For the white screen, does it happen if you launch the game in windowed mode? The option is with the other graphics settings.
If that doesn't help, try shutting down any other apps you normally use before launching Sims 4. Disable the EA App in-game overlay as well; the option is under Settings > Application.
