I'm also having crashes for the first time, and when I say 'having' it's crashing every time I open my main file. It started gradually so i made a copy but both are crashing as soon as opened. Older (much older) files work. Thought it could be a dodgy picture causing it, but have downloaded publisher on a small notebook and the file works fine on that. Copying even bits, never mind the whole thing, onto a dongle and importing it onto the main computer still causes Affinity to crash when I open. Very worrying!
I deleted and redownloaded Affinity but the problem persists, so it should be something to do with the actual computer not the program itself, seeing the file opens on another. New computer then, pronto, unless there's an answer out there.
Update: Sounds mad but it crashes every time I click page 4 on any document! Always page 4 even if it's completely blank.
Update 2: Tried clearing everything with the ctrl click, still crashed, bought another computer.
