Hi Mr Hall, I experienced the same problem and thought it might have something to do with permissions. I opened a window in Finder, went to Applications > Affinity Designer, then command-i for info. At the bottom, sharing & permissions showed system: read and write, wheel: read only and everyone: read only. Normally it says (me), admin and everyone. I changed wheel to read and write, restarted the application and now am able to save again. Hope this works for you too : )
