Game crashes every time I try to place Book Nook furniture

emwherr  Try forcing the game to run in DirectX 11 mode.  Open the EA App, click Sims 4 > Manage > View properties, and add -dx11 to the command line box.

If that doesn't help, 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.
