@NyxKere666 Just to be clear, are you using the same computer for Sims 4, and if so, are you using the same account on the computer? Please let me know what antivirus the affected computer uses, if any. And to be thorough, please run a dxdiag and attach it to a post.

No, we each have our own, so he's using his PC for it. But iirc, you're able to install it on multiple machines right? I think I did so in the past on laptop and my desktop. And I'll attach the dxdiag, but his PC should be able to run Sims 4 flawlessly. He's never had any issue running any game before, especially high intense ones. And he doesn't have any virus protection besides the built in from Win 10.
@NyxKere666 Yes, you can install Sims 4, or any Origin game, on multiple computers, and it shouldn't be an issue as long as you don't try to sign into Origin on multiple computers at the same time. The reason I asked is because if you two were using the same computer, and this issue affected your fiance but not you, there would only be a narrow set of potential causes. The fact that this happens on an entirely different computer opens up more possibilities.
Please start with a clean uninstall and reinstall of Origin:
Next, download the full Origin installer and run it. Here's the direct download link:
http://download.dm.origin.com/origin/live/OriginSetup.exe
Be sure to run both the installer and Origin itself as an admin: right-click on each and select "Run as Administrator." When installing, Origin will list a number of settings it would like to enable: open at Windows login, keep Origin and games up to date, share hardware info, etc. Please disable all of them, at least for now, even if you want those options present at some later point.
You may need to repair Sims 4 afterwards: open your Origin game library, right-click on the Sims 4 icon, and select Repair.
