Game stuck loading after newest update.

@SuperblySim and @valeriacor  As a test, please try playing in a clean user folder.  Move the entire Sims 4 folder out of Documents > Electronic Arts and onto your desktop, and when you launch the game, if it launches, a clean folder will spawn with no content.  (Your saves and other content will be intact in the folder you moved but temporarily not read by the game.)  Don't add anything to the new folder yet; just let me know whether you can get far enough to start a new save and play in live mode for a bit.

If you get an error when trying to move the Sims 4 folder, or it copies rather than moving, let me know.

If this doesn't help, please run a dxdiag and attach it to a post.

I was able to solve the issue by uninstalling the game on Steam, deleting the folder from my documents, and reinstalling. Unfortunate for us players who have metered internet connections, but it did work. 

@SuperblySim  Glad to hear the game is working now.

@valeriacor (and @SuperblySim if you run into the issue again) Does the game work if you launch it while your computer is offline? Sign into the EA App and put it in offline mode, then disable wifi and/or disconnect the ethernet cable before pressing Play.

I attempted launching the game while offline before I had fixed it, and that did not help. I also ran a dxdiag before posting on this forum, and still have it saved. If you'd like to see it, I've attached it below. 

@SuperblySim  I do appreciate the dxdiag, as well as the data point about offline mode, and will keep those Sims 4-related errors in mind for any other threads about the same issue.  The important thing though is that you can play again.
