store.receiptRequest causing crash on OSX

Trying to submit an update to the Mac App Store for a game that now uses IAPs and getting a crash when calling store.receiptRequest, this works fine on iOS just not Mac App Store builds.

When it gets called it requests I login with my app store account ( unless I’m already logged in ) and then upon submitting it crashes. If already logged in then it just crashes.

Below are the crash files as provided by the review team.
