Affinity Design Crashing when the Slice panel is clicked on in export persona.
It's not happening in all files - but happening with some files. I have attached one dummy file to which is crashing on my system. Steps to reproduce the bug: Open the attached file. Go to export persona. Click on the slice tab - and it crashes!

I am running affinity designer on Windows 10 64Bit, Intel i76700 16 GB ram and 6 GB Nvidia Graphics GTX970M card.     Business card bug report AD 2019-09-07.afdesign
