In case the error is still coming after trying all the general steps, then you can move to the other given workarounds.
Fix 3: Try Deleting The Savedgame File
This workaround is something you may not want to try as it requires you to delete the savedgame file under the game files.
Deleting the savedgame file may resolve the error but you will lose all your cars and achievements, and your user level and speedpass progress will be the only process that will carry over.
