I go to the crafting table, and then click the button to go from Craftable to All. Scroll down to a banner and then click the RB  and the game crashes. If it doesn't crash the first time you are in the crafting table then exit out of the crafting table and go back in. You will have to go back to the All crafting portion and then scroll down to a banner and press RB and it will crash. The error message is "The software was closed because an error occurred." with no other details and just an OK button to press. There is also no way to take a pic or video as once the game dies the video option doesn't work. It is repeatable and I am able to make it happen over and over. One last thing to note is that when doing this I do not have the items to make a banner in my inventory.

Edit: Looking at my pro controller the button is just labelled as R.

Edit 2: Playing with this more, it just happened when I scrolled down to a rocket. So it's not just happening on banners.
