If The Sims 4 fails to save your settings, this indicates there might be a problem with the Options.ini file. This file stores your in-game settings. Corrupted or incompatible settings could prevent the game from saving your settings.
Back everything up and follow the troubleshooting steps below to solve the problem.
How to fix the issue where Sims 4 settings won’t save
Remove the Options.ini file
To troubleshoot the issue where The Sims 4 won’t save your settings, move the Options.ini file to your desktop. Navigate to Documents/Electronic Arts, open the Sims 4 folder, and you’ll find the Options.ini file there.
Start The Sims 4 again. The game will generate a new Options.ini file. Do all of your in-game settings again. Then restart the game and check if the new settings stick.
Whitelist your game files
If you’re using an antivirus, make sure the program is not preventing The Sims 4 from making changes on your drive. Go to your antivirus settings, and add the game files to the Exceptions list.
Disable cloud storage programs
If you’re using OneDrive or other cloud-storage programs, don’t forget to disable them before launching The Sims 4. These programs don’t always play nice with game files.
Repair the game files
If your game files got corrupted, you should be able to fix the problem by using the built-in repair tool. Launch Origin, go to your game library, right-click on The Sims 4 and select the Repair option.
Restart the game and check if the issue has been resolved.
