PDF Cannot be created/opened

[glmbp2020]

I am unable to open a PDF when the Blair font is used. Attached are the error messages I get when I try to export to PDF. I get Error code 58

but the expected PDF appears in my folder. When I try to open this pdf file I get the other error message.

When I change the Blair font to a more standard one (such as Arial), the export to pdf works fine. What's the issue?
