White screen on startup

@abzadaisy  Your dxdiag doesn't list any Sims 4-related errors, which is not entirely surprising given the initialization error.  This error is typically related to an antivirus blocking the game, so please set exceptions in your AV for TS4_x64 and TS4_Launcher_x64.  Set one for EADesktop.exe as well.

If you still can't play, please look for new errors in the Reliability Monitor.  Click Windows key-r, enter perfmon /rel in the run box, and you'll see a chart of errors and updates with a column for each day.  Today is on the right.

Look for an error that happened at the time of your most recent attempt to open Sims 4, specifically after setting the exceptions.  If you find one, right-click the error name and select "View technical details," then copy that information and paste it here.  The Reliability Monitor doesn't always update right away, so if you don't find anything, check back in an hour or so.
