White screen won't launch

0zwg2qumbdly​  Try deleting Options.ini in Documents > Electronic Arts > The Sims 4.

If that doesn't help, edit the new Options.ini that spawns to set fullscreen to 0 (zero).

If that doesn't help either, please provide a dxdiag.  Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop.  From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.
