The available menu options are decided based on the current selection in the Solution Explorer - the type of project selected or, if no project is selected or the project is not OpenAccess enabled, then wizards that apply for the entire solution.
I tried reproducing the crash with a solution under source control but again all went well. Currently there is no log that you could check for.
Does the same problem occur on the source controlled solution if you restart Visual Studio? If yes, do you see the next set of 4 steps for Reverse Mapping or does it crash immediately on clicking 'Proceed' for 'Yes, generate classes for my tables'
