Uninstalling KB3132372 will fix it, however this isn't a great solution:
a) It's a security patch for flash, removing it makes your PC vulnerable
b) If you're on Win10 it will just re-install next time your PC updates
We've already opened a support ticket with Microsoft a few days ago about it, and you can use the temp build we put up in the interim. Short of Microsoft fixing the issue in their embedded browser , we're looking into using Chrome instead in the future.
