When you press "Play" all options to edit or change the profile are still available.

How to reproduce

1. Create a profile called "Profile 1" using the latest version
2. Create a second profile called "Profile 2" that uses an older version and also uses a different game directory
3. Open the game with "Profile 2" and select a language other than English
4. Close the game
5. Select "Profile 1" and press "Play"
   While the launcher starts the game, select "Profile 2"

You should now be using the game version of "Profile 1" but the language of "Profile 2"
