Game Suddenly Started to Crash at Loading Screen after Startup

@nekusakuraba07  Please post a new dxdiag.

And for good measure, please try playing in a new admin Windows account.  Make it local, as in, don't link it to your Microsoft account.  You'll be able to launch Sims 4 without reinstalling anything, but your user data won't be available.  That's fine and actually helpful for the purposes of this test.  The idea here is to see whether the problem is contained to your main Windows account or is more global.
