Failed to open TIFF file

[sportyguy209]

Hello:

My Mac is the latest 16" MacBook Pro with 24 gb of memory. The apps and system are the latest available.

I find this problem with all Affinity apps (I have Publisher, Photo, and Designer), but I've been working with Photo a lot recently.

I scanned a bunch of photos on my Epson V800 scanner and saved them as Tiff files. I opened a random number like 10 and they would be fine. I'd crop them, save them, and everything worked as expected. I'd go to File/Open and try another 10 or so. This might work once or twice until I'd get the "Failed to open Tiff file" error message. If I quit, then opened the next group of photos everything worked fine. So, it isn't a problem with the files or my permissions, but with a cache or something in Affinity. Because the problem would go away when I would relaunch. I find similar problems with Designer and Publisher. I'd be working with some files and then try to save them, and I'd get a message that I can't save them. I'd have to quit, open the documents up again to be able to save them. It's a bit annoying because I have to remember to save very often regardless of what I'm doing because I can't count on the app to save consistently.

Is this a problem that other people are having or is it just me?

Thanks,

Peter

Hi sportyguy209,
Are you using the Mac App Store version? How many fonts do you have installed in your system?

[sportyguy209]

Yes, I have the Mac App Store version of Designer and Photo, but Publisher was purchased directly from Affinity.

I had a similar problem with Affinity, I think it might have been with pdfs that I had too many fonts, so I've paired them down drastically. According to Font Book, I now have 497 Fonts installed which includes all the variations. For example, I have AmsiPro as one font, but it has 46 variations. Most of the fonts are Apple fonts.
