Monopoly Sudoku

Monopoly Sudoku will not load.

For the past few days, all I get is a white screen.

As a result, I am unable to complete the Tex's Lucky Spinner Event

since one of the challenges is Monopoly Sudoku

(Open 10 Chance Cards before the Event ends).

The Event ends in 2 days: Monday - September 28th.

Does anyone have a suggestion on how to fix this?
