I'm on newer version of Windows Insider Preview (build 17704) and your game still won't launch. Your comment belies that it is known by your dev teams that there are issues with your game ever since 17661. I have over 60 titles across Steam, Origin and Battlenet and I have yet to encounter any such issues of this severity related to Windows Insider Preview builds or otherwise.
Are you giving up on working through this? I'll send you whatever you need - I'm 60% through the game I would hate to just write it off.
