My Sims4 Crashes on Startup

I have this issue for months. I did not pay enough attention to know if it was when a specific update came out, but I know it's been happening since at least June. My game crashes upon launch every time - it gets to the Sims4 and then completely crashes.

I have uninstalled/reinstalled/repaired countless times. I have tried launching from both EA and Steam. I used to play with mods, but when the crashes started I deleted all of them - so no mods to worry about. Reading through the other posts here, I've also tried checking my ConfigOverride, using a clean game folder, updating drivers, launching in windowed/fullscreen. I'm not sure what else to do ?!

I have put hundreds of dollars into this game and 800+ hours, and I just want to play again. Please help! I'm at my wits end. I have attached my dxdiag. THANK YOU!
