S4SH7MI Does this happen with a new save too? Please start one, with your Mods folder removed, and see what happens.
If the new save is affected, 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.
If the new save is fine, I'd like to see a lastexception from your main household in your main save. 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.
Please continue to test with your Mods folder removed. You don't need to save your progress.
