Game crashes on save..

PinkFlissy KleinesVivil  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.

Please also let me know whether OneDrive is running on your computer.  Even if you never use it, it could still be interfering with Sims 4's ability to save.
