Yes the file you repaired is now working fine again. Thanks again for your great help !

I was working on a very large file yesterday and Publisher suddenly closed. Now I can't open the file. I can open other files, but as soon as I open that specific file, Publisher closes in a split second, no warning, no error. I had a multi-month project delivery yesterday, luckily I had exported most of the work already, and for what was missing, I at least put something together from past versions. But I do need to recover the editable file.
I cannot share the file, it's “confidential”, 712MB, 70 pages long, with embedded files.
Before crash, I was copy-pasting 2 picture frame elements, with one tiny (150px) image each, from one page to another.
When I open this file, Publisher just closes without warning, whether there are other files open or not. There's no error afterwards, no “Affinity Publisher stopped responding” or “Report crash”, nothing. If another unsaved file was open at the same time, that one will be recovered upon re-opening Publisher, but not the file in question.
Where are the auto-saves saved? How I can access auto-saves? Where are the settings for auto-saving? Couldn't find those in the settings. Is there an error log somewhere I can access to at least see what happened? How can I avoid having a file just break like this? Having a corrupted file on the day of a very large project delivery not only put in line my sanity, but also my job! Thanks in advance

Publisher looks very promising, and I really would like to use it, especially since i moved to Catalina, and ID CS6 won't open anymore.
But save files should never become corrupt. Never, ever. No matter what.
Let me repeat that. Never. Not for programs like Publisher, which often are used for ”mission critical” work – with tight and immovable deadlines.
I've used Publisher now for a couple of fairly large projects (tabloid size, 20 pages, with the usual assortment of linked raster and vector images of different formats and color systems), and I regret to tell you I find myself back in PageMaker days, when a whole day of work could disappear in a puff of smoke because of strange, hard to reproduce crashes and subsequent corrupt, unopenable save files. Now, after saving a lot of "known last good state" files, and after I fiddle around with saving linked images in another format, or clicking different things in the Metal/One GL acceleration settings, or changing around options in the pdf export settings, I do manage to (barely) get my Publisher jobs to the finish line…
You can say a lot about Adobe and InDesign, but ever since I started using  ID 2.0 waaay back in 2002, I have never come across a situation where an ID save file would be corrupt and unopenable, or for that matter that the app would crash when doing normal stuff like moving around in the document, or exporting a pdf. This one Adobe really nailed.
Strangely, some problems, sometimes, seem to resolve when I restart the machine. Are th eproblems then mainly memory corruption issues? Running out of memory? Or something to do with the GPU acceleration? Or a combination? I can't pin it down.
Regardless, robustness of the app and the save file should now be of the utmost, highest priority for the Publisher developers, even at the expense of new shiny features (though i of course eagerly await footnotes…)
Rant over.

I updated my Mac to Catalina, and now Affinity Publisher doesn’t open at all. I even installed the latest Catalina update, 10.15.1, to no avail. Is there a way I can make Publisher work again? When will Affinity release the update to their suite to make it compatible with the new Mac OS?
