This is not happening in the release version so I suspect it is due to the recent changes to Viewbinding in this PR.

cc @nbradbury would you be able to take a look at this one since it looks related to changes made to this PR during the Viewbinding changes. I am not able to reproduce this in the release version just the latest develop

This crash happens in all screens that use WCMaterialOutlinedSpinnerView and WCMaterialOutlinedEditTextView, as we try to access the not initialized yet binding in setEnabled when it's called from the base constructor.

I'll submit a fixing PR, as it's blocking me from fixing merge conflicts on shipping label PR.
