Woof. Works like a charm. I had a lot of fonts enabled, so it was not a problem to deactivate a bunch of them. And now Designer opens as it should. Thanks for the help. Mark

Wow. Thanks. Leigh. In fact I did get my AD from the Apple App Store and I use Suitcase Fusion (and an old version at that). I had no inkling it might be causing the problem. This is not a quick fix. But I'll spend some time on it and report back. My guess is, this will take care of the problem. At this point I'd prefer to ditch Suitcase Fusion completely, but it has saved fonts here and there on the computer and I can't predict the effect of just deleting the app. But I can certainly deactivate a lot of fonts. Is there a way to sidestep the problem by downloading a new AD from the Serif website, sort of a replacement app? Or would I have to buy it again? Anyway, thanks. I'll report back once I've accomplished this. Mark

I tried it. I unchecked. Then I deleted it completely. Then I added it back (it arrived checked). After each step I tried opening a .afdesign file. And I always got the "Permission Was Denied" error. It's as if the program is broken. As mentioned, I've seen errors similar to this reported on this forum. Just never a solution. Do the developers read these posts?

Hi Bruce, Thanks for responding. Yes, I'm on the newest version of Big Sur, 11.3.1. I wish it were that simple. My Security & Privacy preferences show 2 appropriate folders: "Full Disk Access" and "Files and Folders." Both Affinity Designer and Affinity Photo appear in Full Disk Access. Both are checked. Both also appear in Files and Folders, but they're grayed out. Beneath each is the notation "Full Disk Access," which leads me to believe that this is just a reference to the other folder. Although I find it odd that AD can't open its own files, in fact it can't seem to open anything. I've tried .eps, .ai, .jpg, .webp, .png, and .tif and get the same "Permission Was Denied" error. For .svg and .psd files I get a "File Not Found" error, which is puzzling because I'm finding the files by clicking on them and because they open in other programs. I have opened .afdesign files in Affinity Photo. It's only Affinity Designer that balks. It's as if AD were somehow corrupted. But after first seeing the problem, I downloaded and installed a fresh copy. No change. Any other suggestions?

Lately I haven't been able to reopen Affinity Designer files. These are files I created and saved with the program. I bought AD about a year ago when I had an older iMac. I've since changed to a silicon Mac Mini. I have the latest version of AD. When either clicking on a .afdesign file or trying to open it from within the program, I get this: Of course I checked permissions of the files, and they're all set for read/write. I tried tossing and redownloading AD and it made no difference. I've seen this general problem posted on this forum but never with a solution that helps me. Has anyone figured out how to fix this? Thanks. Mark
