As others have experienced, I ran into the issue with Microsoft Edge failing to launch with MBAE running with Build 14936.  Uninstalling MBAE, deleting the Program Data folder did not help.  With numerous reports in Feedback Hub (including mine), I let it ride since I was not about to disable MBAE and a Microsoft Engineer had responded that the issue was being investigated. Fast forward to new Build 14942 installed 07Oct2016.  The same issue with MBAE continued.  I reported it both in Feedbac
