This is happening on Windows 10 Pro 64-bit with Affinity Designer 1.7.2.471.
I have this one file that crashes Affinity Designer when switched to the Export Persona. I can manually export each Artboard fine in the Draw Persona.
It gets more complicated, though. I have this file link-embedded in several other files (Problem file > other files). Those other files can be switched to the Export Persona fine, but clicking on the Slices pane causes a crash. Exporting from the Draw Persona still works in those files.
But it gets weirder. I have one file in which I have link-embedded one of those other files with the problem file link-embedded (Problem file > other file > this one file). It does not cause crashes when switching to the Export Persona or using the Slices pane, and can successfully export all Slices as expected.
I have attached the problem file.
P.S. I know it isn't supposed to be possible to link embed files in Designer 1.7.2, but I needed it because I keep editing these files and link-embedding made replacing old versions much easier. When I needed to reload the link-embedded files, I would just open the file in Publisher and update it there.

Welcome to the Serif Affinity forums 
To all readers,
Sorry about this regression I have escalated the issue to have it fixed in the next patch.
For those on tight deadlines please avoid the slices tab or if that's not possible revert to 1.7.1 from here (works as a trial for those who bought Affinity Designer from the Windows Store)
