Re: Sims 4 Cats & Dogs white screen

Could you give repairing the game a try? Right-click the game in Origin and choose 'repair game'. 

Could you post a DxDiag? This gives us a bit more information into your system and what is going on.
Feel free to delete any personal information like the 'machine name'. You can attach the DxDiag to your next reply in this post.
You can read about how to gather your DxDiag over here:
