jazzshoes2908 Did you happen to download any content from the Gallery into this save? If so, please try again but with fresh sims on an EA-made lot, or one you build yourself for testing.
Otherwise, please try playing in a clean boot (not another reset, just a way to disable background apps):

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 the game freezes or crashes in a clean boot, 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 even being offline doesn't help, please let the game crash, then create an EA App error report and post the report ID here.

An EA community manager has asked (in a different thread) for report IDs from people with crashing not explained by an issue on the user side and that doesn't respond to the usual troubleshooting. If the clean boot doesn't help, I'll merge your posts with that thread and make sure the report ID is passed along.
