Affinity Photo quits unexpectedly with the error message "unhandled exception code: 0xC0000005". Bug or wrong Preferences

Recommended Posts

I'm working currently on restoration of old photos and use mainly the "inpainting Brush tool".


Last time AP crashes again and again, sometimes unexpectedly and times when saving a file. The error message is "Affinity Photo no longer works" or "untreated exception code: 0xC0000005". A crash report is nowhere recorded, neither in CrashReports from AP nor from MS Windows.

Unfortunately, my work becomes not restored and all changes are lost afterwards.

From frustration I have re-installed Affinity Photo completely, unfortunately, the same problem is available under Windows 7 (64-bit) as well as under Windows 10 (64-bit).

At some point I noticed that the "AP History" was mainly responsible for the error "0xC0000005". From a history size with over 600 steps, the AP can doesn't manage these.


Thereupon, I deactivated the function "Save History With Document" which is important to me. Since I have no "unhandled exception Code: 0xC0000005" error and can save my documents, however, I also see no more History of the last edit:(


Question: Is it a "bug" in the software or the "Preferences" are set wrong??



For your help I am very grateful,

Hi ChristAlix,
Just to be sure you are experiencing a lot of crashes when using the Inpainting Tool with 'Save History with Document' enabled? If so would you be able to upload a document with the Save History enabled please? Please use the link below to upload to our internal support Dropbox.


We can then look into trying to reproduce it with your file.

I too have see this error, but dismissed it thinking it was something I had done.  Using Windows 10, but not sure if the error occurred on laptop or desktop.  If it reoccurs, I can send in the file, but at this point, I suspect you won't need it.
