Sports Interactive have just released the first hotfix patch for the final retail version of Football Manager 2018.
The 17.1.1 patch merely addresses a stability issue related to starting a career game in Sweden.
Released: 10 November 2017
To update you will need to close down Football Manager 2018 and re-launch for it to update. If this does not work for you or you feel it has not updated, you will need to restart Steam.
Even if that doesn't do the trick, then verify the game...
