To create a new profile.
- Start the launcher.
- Login to the account in question - but don’t click play to enter the game.
- Click on the Cog wheel next to the account in the launcher window.
- Click on manage profiles.
- Click on new profile and give it a name like ‘testing’ or something and press enter.
- Click close.
- Select the checkbox for the newly created profile.
- Close the options window.
Now click play, the account should now launch with the new profile you just created. The newly created profile will have its settings restored to the default options, hopefully resolving your issue.
