Angeline1398 Okay, please remove ALL packs and play with only the base game. I'm not saying you need to stop using your packs, only that I'd like to know whether the game works with minimal content present. Please try a new save in a clean user folder other than having the listed NRaas mods present. As in, move the existing Sims 3 folder out of Documents > Electronic Arts and onto your desktop, open the launcher to spawn a clean folder, copy over only those NRaas mods and the mods framework required, start another save, and see how it runs.
If this save freezes, please try again, except in a clean boot. Here's how to do it:

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 3 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 this 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 you do find the problem and the game is stable again, you can start adding back your DLC. Stuff packs are fine, and the first three expansions (World Adventures, Ambitions, Late Night) probably are too. After that, add any of Generations, Showtime, Supernatural, and University Life one at a time, and keep testing. If all those are fine, you can add Island Paradise or Into the Future, then the other, then Seasons, then Pets.
Please don't add any other mods or custom content yet, and don't test your old saves. The idea is to get the game to a stable point, then add back content until it stops working again (if that happens), then back off just a bit from that point, and figure out what we can do from there. I know it's al ot of testing, but at least you can find out somewhat quickly whether there's a problem.
