I keep getting “PNG export error” while exporting the whole project (full page) to any graphic format (PNG, JPG or whatever). Sometimes I can export it just for the first time, before I add any assets (photos, svg files etc.). But the next time I try to export I get this error message. It occurs just from the beginning (c.a. Lunacy 5). The only possibility to export the whole project is via PDF export. But then I have to generate JPG in another app (Affinity Photo).
My OS is Windows 7 SP1. Have no access to Win10 (my primary OS is Linux, I use Windows just for design software).
