"java.lang.IndexOutOfBoundsException" error after 1.13 install

Updated to new 1.13 version, clicked Play then the following appears "Game Crashed - The game crashed while initialising the game" (see attachment "game_crash_1.jpg).

Clicking "Show more details" produces the message: "The game crashed whilst initializing game
Error: java.lang.IndexOutOfBoundsException" (see attachment "game_crash_2.jpg).

Please see the attached Crash Report "crash-2018-08-08_17.32.47-client" (hopefully it will say why this has happened).
