@4aad3afd4a94c4e9 The important detail here is not the manufacturer or speed of the memory but whether it's on the motherboard's list of supported RAM. For that, you'd need its exact product number, which is much longer and should be available on the product page where you're looking to buy. As an example, on this page:
https://www.bestbuy.com/site/corsair-vengeance-lpx-cmk32gx4m2e3200c16-32gb-2pk-x-16gb-3200mhz-ddr4-c16-dimm-desktop-memory-black/6448611.p?
the product number you want is CMK32GX4M2E3200C16.
You can find documents listing all the memory modules your board supports here:
https://www.gigabyte.com/Motherboard/GA-A320M-H-rev-1x/support#support-doc
Your CPU (Picasso) family isn't listed, so check the lists for Raven Ridge and Pinnacle Ridge, the closest to your CPU's family. Memory that isn't on these lists might work, especially from a reputable brand like Corsair, but there's no guarantee.
Your motherboard supports RAM speeds up to 3200 MHz, but that's techically an overclock, so you'd need to enable the higher speed in the BIOS. There should be a simple button or dropdown menu for that; it would be called something like D.O.C.P.
You also don't need 32 GB RAM, at least not for Sims 4. The point here is to have two modules so you get dual-channel speeds. So a 2x8 GB kit would be fine. If it's cheaper, you can just buy one that matches what you already have installed. That's not to say you shouldn't get new memory, or 32 GB rather than 16, only that it's not necessarily any better than working with what you have already. And whenever you buy or build your next computer, whenever that is, you won't be reusing this RAM—current CPUs and motherboards all support DDR5, which is a lot faster and also utilizes a different slot that wouldn't take a DDR4 module.
I want to reiterate though that it's worth doing some testing before spending any money. Playing with sound disabled is a helpful test, as would be playing in a clean boot, even though neither is a long-term solution. It's simply helpful to know where the problem is originating. For 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.
Your dxdiag shows a couple of generic Sims 4 errors and some Windows update errors, probably nothing to worry about. Still, for the overall health of your computer, it's worth running a couple of basic checks of your Windows system files:
- Hit Windows key-X
- Choose either “PowerShell (Administrator)” or “Windows Terminal (Administrator),” whichever option is offered
- Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes, and enter
- The system will start validating soon. If it throws an error, please list it here
- After it reaches 100%, hit Windows key-X again
- Again, choose “PowerShell (Administrator)” or “Windows Terminal (Administrator)”
- Inside the window, copy and paste “sfc /scannow” without quotes, and enter
- Post the message you receive here
Restart your computer, hit Windows key-i, select Update & Security, and click the box to check for updates. If any install, restart again afterwards.
