Please add a cancel button here. It has frozen at 15% and I don't know why (powerpoint file only 2MB), but besides that, I have to do the nuclear option of ctrl+alt+delete to cancel this process. This too, of course, closes Studio down entirely forcing me to start it up again when simply a cancel option would do. Or, ideally, throw an error with a clear message instead of freezing which then aids in figuring out why it froze/threw an error to begin with.
