Odd error with Configurator 2

I've got an odd issue with Configurator 2 when trying to build new iPads.

I've fully updated the Mac and apps. The iPad downloads and installs the latest OS happily, but when I try to prepare, add a profile or add a wallpaper, it throws up this error.

An unexpected error has occurred with "iPad".

The operation couldn't be completed.
(NSMachErrorDomain - 0xFFFFFFFFFFFFFF (-1)
[sys = 0x3F, sub = 0xFFF, code = 0x3FFF (16383)])(NSMachErrorDomain - 0xFFFFFFFFFFFFFF (-1)
[sys = 0x3F, sub = 0xFFF, code = 0x3FFF (16383)])

Any help would be hugely appreciated!
So it turns out despite the appstore saying there we no updates, uninstalling and reinstalling config 2 sorted it.
