I didn’t mean to say that the reason for a CTD is allways the dev-mode… but it can cause issues and often is hard to find out for us.
A note about CTD issues:
discussions to find reason for special user CTDs might be better within one of the existing CTD threads in Issues-Category. ( Example Link ). Please report system specs, driver versions and possible existing windows event viewer log. Be aware, for Issues with VR exist an own VR-Issue-Category.
