@98019801980199 Doing a clean uninstall and reinstall of Origin and Sims 4 would be my first suggestion, and if you want to be as thorough as possible, use Revo:
Start by uninstalling Sims 4:
- Put aside your Sims 4 folder in Documents\Electronic Arts and rename it to something that doesn't include the words "Sims 4."
- Download Revo Uninstaller (the free version is fine) from here.
- Launch Revo, select Sims 4 from the list, and click Uninstall.
- Once the game is uninstalled, select "Moderate" under "scanning modes," and click Scan.
- Review the list, in case there's something you want to save; otherwise, click Select All, and then Delete.
- Close Revo, and restart your computer.
Next, uninstall Origin:
- First, clear Origin's cache.
- Quit Origin, then right-click on the Task Bar and open the Task Manager. Scroll through looking for Origin entries. If you find any, click on them and End Task.
- Launch Revo again and uninstall Origin, and when it's uninstalled, select "Moderate" again and Scan.
- If Revo finds any remaining registry entries, select all, delete, and click Next.
- Revo will display "Remaining Data and Folders. Select all of them except for the "Origin Games" folder, if it appears. (This is where other Origin games are installed by default.) Delete the rest.
- Close Revo, and restart your computer.
Next, download the full Origin installer and run it. Here's the direct download link:

Be sure to run both the installer and Origin itself as an admin: right-click on each and select "Run as Administrator." When it's reinstalled, download Sims 4; you can just download the base game, to save time, if you want.
I'd also try playing in a new admin Windows account, since it's a simple step and does address certain other issues. And let me know what antivirus you use, in case it's a known problem.
