JiHaeSoo Does using Load Game work? Please try loading a different (previously unplayed) household within the same save, and a household in a different save. It's possible that the only issue is loading into your main household or the one save. If you don't have other saves to test with, create a new one.
If other saves work, please open Documents > Electronic Arts > The Sims 4 and delete any lastexception files you see. Try again to load this save, and if and when it doesn't work, look for a new LE. If you find one, open it (Notepad is fine), copy its text, and paste it into a reply here.
If you can't load a new save 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.
