Can't quit Publisher after opening a copy of an AFDESIGN document

[GarryP]

Double-clicking an AFDESIGN document in Windows Explorer runs Publisher - see related issue here: https://forum.affinity.serif.com/index.php?/topic/69657-affinity-logo-change/
When asked what to do with the document - Cancel, Continue or Copy - I opt to open a copy.
The document opens and I opt to convert artboards into spreads, all seems fine.
When I then try to close Publisher - without making any other changes - I get a dialog box as shown in the attached image.
After waiting a few minutes I still get the same message when trying to close Publisher.
Closing the document itself works fine but then when trying to close Publisher I still get the same message.
The only way to quit Publisher after opening a copy of the document is by using the Task Manager.

Hi GarryP this is a known issue with the make copy option. The team are working on sorting this at the moment

Thanks
