Export to PDF with a specific font family crashes all three apps

[Racey]

Font Akwe Pro applied to frame text or artistic text causes Affinity Publisher 2 (also Designer 2, Photo 2 and now all three version 1 apps) to crash when exporting to PDF as subset font. To reproduce, place text in any document, apply any Akwe Pro style to it, then export to PDF. The app crashes and on restarting it, Terminal consistently offers up the following [extract]:

'2022-11-13 13:58:13.724 Affinity Publisher 2[2509:47797] CoreText note: Client requested name ".SFNS-RegularItalic", it will get Times-Roman rather than the intended font. All system UI font access should be through proper APIs such as CTFontCreateUIFontForLanguage() or +[NSFont systemFontOfSize:].

The font files have been validated by Font Book. Latest versions of InDesign, Pages, Word all output the font to PDF (as subset not curves). Font was working just fine in v1 until I upgraded to v2 of the Affinity apps.

iMac running Big Sur (11.7.1). Identical error reproduced on a Macbook Pro running Monterey (12.6.1).

".SFNS-RegularItalic"

This issue may be related to fonts, but I doubt it is related to Akwe Pro.
The dot before the font name above means it is a Mac system font.
So I am not sure why that is being included in your document.
macOS TTC files do sometimes have a "dot" font and a regular font (for the same font).
Maybe there is an issue with that on Macs now (the TTC files).
Can you attach at least one page of the document which demonstrates this issue?
Then others, including other Mac users, can take a look.

Below is a test of Akwe Pro Regular Exported to PDF (on Windows 10),
and then exported from the PDF to a PNG. Working fine here.

Thanks for taking a look. The attached file crashes for me. The SFNS files are separate ttf files in my System/Library/Fonts/ folder.

Well that is quite bizarre - instant crash for me too on Win10.
Changed the fonts to Akzidenz-Grotesk Next and it exported fine.
Late here, will look closer tomorrow.

I've reproduced the crash after sourcing that font and exporting the attached PDF. It's now logged with us.

Thanks for the report
