autumnkinloch I apologize for the late reply. Holger1405 and I were going over your CBS log, and one thing that confused us was that there's no trace of sfc running in the log. But I realized that the log doesn't go back far enough—its oldest entry is from December 2, and you posted the results from sfc in November. So that explains the issue, but the log is also not useful for troubleshooting purposes.
Anyway, please try playing in a clean boot:

The one service to leave enabled is the EABackgroundService, which the EA App needs in order to run. Disable the rest as described.
When you reboot your computer, go through the Task Manager's background processes list shutting down any service that doesn't absolutely need to be running, for example anything from MSI Afterburner to RGB software might still be enabled. If you accidentally kill a critical process and it doesn't restart on its own, just reboot your computer again.
Don't open anything other than Sims 4 and the EA App while testing, not even a browser window.
If this helps, you can selectively reenable services until you find the culprit, then either leave that disabled or (if it belongs to an app you want to keep using) let me know what it is so we can try to fix the underlying issue.
If it doesn't help, please try again, except with your computer offline. You can sign into the EA App and put it in offline mode, then disable wifi and/or disconnect the ethernet cable before pressing Play.
If that doesn't help either, please post a new dxdiag, run immediately (within a few minutes) after you've tried the clean boot while offline.
I do want to say that your computer probably isn't ever going to run Sims 4 perfectly. But the game should work, maybe with some extra help.
