I have the same problem on my Mac since the last Update of Affinity Designer and also Photo. All Images are embedded. If I try to open an document that worked a couple of days before with the old versions perfect - it is not possible to open it any more. The Dokument File Size is 86MB. Affinity crashes directly on start when i try to open the document. Tried it several times with all affinity Apps including the new Publisher. Always the same. It crashes immediately. Hope there will be come a working update soon - otherwise it is a real problem for all affinity users because working is not possible if one can't access documents. Affinity Team please help and release a new Update!
