Hi,
It seems there are many threads around Affinity Publisher 1.7.3 crashing on save. In my case, I can open my afpub file, but cannot save it, even when I don't make any change to it and use "Save as". I tried:
Save or Save as = crash
Deleting all pages except first then save or save as= crash on save
Removing all complex layers (graphics with layer fx) then save or save as= crash on save
Deleted all pages, emptying first page, deleting all masters then save or save as = crash on save
Exporting to PDF : it works.
Open said PDF back in Affinity Publisher then saving it as afpub : it works.
So the problem seems to be with something in the afpub file that is no longer present when converted to pdf and re-opened back into Publisher.
I need your help developers please, as the culprit does not seem to be related to the visible content (see trials # 4 and # 6).
Here are the afpub file as well as the Apple crash report.
