affinity photo, publisher crash on saving

[Artworkzzz]

I'm editing a large file in Affinity Photo.  470mb greyscale. Was moving between Publisher and photo for various tasks, and then Publisher started crashing.  Moved the file to Photo and seemed ok for a bit, then it too has started crashing.  I re-open the file, do 4 or five brush strokes, save and its ok. Repeat, ok, then the third time crash.

That behaviour keeps happening now. Restarted the mac (Macbook Pro 14" M1 running 12.6.3) but same behaviour. See report enclosed.  Seems to be related to the Affinity Store.  The same crash report when Publisher was going down as well.

Right now it's the only app running (or not).  Recently updated to latest version.

Further to the above, tried the same file in Designer, and the same except now it happens every time I try to save.

I tried turning off 'Save History with Document', and right now things seem stable.....

Hi @Artworkzzz,

Could you possibly send me a copy of your document and provide the full crash report files from your screenshots? I can then confirm if these crashes can be replicated with the Save History function enabled. I've provided a private upload link below.

Many thanks

Hi, I'm afraid I overwrote the toublesome file once I managed to return to normal service having disabled history recording.  I do still have the crash reports and am currently still working on the file, this time with history recording switched on in an effort to replicate the issue.  LMK if you want the crash files anyway.  Wil send app file if problem returns.
