The main reason is that OneDrive or antivirus programs are stopping the game from saving changes to this file. Other possible reasons are: not having admin rights, broken config files (with “_tmp” in the name), or the file being set to “read-only.” Now that you’re familiar with the usual causes of this error in Battlefield 2042, try the solutions below that have helped many users fix the problem.
1. Run the Game as Administrator
If you aren’t running Battlefield 2042 with administrative privileges, you’re more likely to encounter this issue. Some users confirmed the problem is tied to permissions—without them, you might not be able to save or change settings, or Battlefield 2042 might not even start. To run the Origin app as admin, right-click the Origin icon and choose Run as administrator. Once Origin launches with admin rights, check if your settings save properly.
2. Remove Temporary Game Files
Sometimes, corrupted or outdated game files can prevent Battlefield 2042 from saving your settings. These temporary files can cause conflicts and need to be removed. In this solution, we recommend deleting the PROFSAVE_tmp file. This simple trick has worked for many gamers.
3. Allow Game Files through Antivirus
Sometimes, antivirus programs can block the game’s files, preventing them from running properly. Some security programs might even mistakenly flag the game as a threat. If you use a third-party antivirus, add the game’s files to the exclusion list to see if it resolves the error.
4. Close OneDrive
A number of Battlefield 2042 players have confirmed that OneDrive can interfere with the game’s files and settings, stopping changes from being saved. Closing OneDrive before launching the game and making changes has helped many users.
5. Check Your Windows Username
Although rare, sometimes having special characters in your Windows username can cause this problem. If you still have issues, check your username and, if necessary, create a new user account without special characters, then launch the game. Now, reboot your system. When your system starts up, relaunch Battlefield 2042 and check if your settings can now be saved.
