Same here, bad scene for months, crashing on every one of my machines like dominoes falling. I'm dead in the water.

I have been using the Affinity suite with great pleasure on my legacy systems, updating years of old projects back to Freehand 9, often by hand. The effort is worth it to get the smoothness of Affinity's tools.
Right now I have just laid out a 96-rectangle outline book layout 3 x 19 worksheet with no content, just a matrix of rectangles and a few bits of type for occasional page numbering. No other graphics images of any kind.
Crash, boom, splat.

So I cannot get any of my work out, and I'm dying here..All these machines crash:
27" iMac (2011) 10.9.5
MacPro 4-core (2009) 10.9.5 
MacPro 4-core (2009) 10.11.6
MacPro 8-core (2008) 10.9.5
MacBook Pro (2012) 10.9.5
Printing to Epson 4880 and P600
Exporting from File menu to PDF as a safety workaround worked once, now crashes.
Printing via driver to PDF crashes every time as well.
Who's got some ideas?
Thank you all,
David W.
