This is a known issue and we are working with Microsoft to release an update. Since Microsoft embeds Flash Player in IE/Edge on Windows 8 and above, the update will be released by Microsoft, not Adobe.
In the meantime, you can uninstall the Microsoft Update (KB3132372) to revert to the previous version of Flash Player.
It looks as though Microsoft just pushed out a patch for this in Windows 10. If you force Windows 10 to check for updates, you should be able to get that now. See post by Chris Campbell here for more details: Re: Flash Player 126.96.36.1997 - ActiveX Embedding Issue
