Lightbox for Knowledge Check Review
I think, in order to do what you are looking to do, you may have to use your own variable to track attempts rather than using the question configuration options. This way, the question can remain active all the time, but the functionality of showing the lightbox would be controlled by your own "attempts" variable.
This is just a rough sketch of an idea, but you could just define a number variable called "qattempts". Each time the user selects submit, or a feedback layer is opened, it would increment "qattempts" by 1. Then, when "qattempts" reaches 2, show the lightbox.
Ensure that you add a trigger to the Master Slide on timeline start to always reset "qattempts" to 0. This means that every new question you attempt, can re-use the "qattempts" variable and it will be 0 each time the slide loads.
