Sims 3 repeatedly crashing at the load screen via EA App

I'm having trouble getting the EA App to successfully load my Sims 3 game. The Sims 3 launcher successfully loads and the game boots, but every time I reach the first game loading screen the EA App crashes. I was also getting the error report "an error on our end caused the launch to fail" but along the course of the fixes outlined below, now the app just crashes instead.

I am running a Snapdragon X Elite core with a Qualcomm Adreno X1-85 GPU 128MB graphics card, 32GB RAM and plenty of storage (brand new computer) on Windows 11. 

I've tried the following unsuccessfully:

• Uninstalling and reinstalling Sims 3 and the EA App (a few times)
• Using RevoUninstaller to fully remove Sims 3 and EA App, and reinstalling
• Running the game using 1 core processor to see if it was my computer's high number of cores
• Disabling EA and Steam in-game overlays 
• Uninstalling and reinstalling .NET 3.5 via appwiz.cpl (which did detect files that needed downloading but did not solve the problem)
• Only installing/running the Sims 3 base game without expansions 
• Un-checking read only on my game folder in C:\Program Files\EA Games and 

  C:\Users\NAME\Documents\Electronic Arts

• Disabling and removing OneDrive, using regedit to reroute my documents and other folders to local
• Allowing the EA App as an exception on my security program 
• Deleting EA App cache

If anyone has advice other than me repeatedly sending crash reports and hearing nothing back from EA, that would be amazing. I'm not super tech savvy but am good at following instructions, so any suggestions would be greatly appreciated. I'm happy to retry any step from above but am all out of ideas of how to start fresh.

Cheers
