If the log stops or errors out after displaying cid font f1, the system is trying to substitute a font but cannot find the specific CID values it needs.
In the architecture of PostScript printers and PDFs, F1 is almost always a font handle or a resource tag. It is not the font's name; it is the printer's internal nickname for the font.

Decoding the Mystery: What is "CIDFont+F1" and Why is it in My PDF?
Have you ever opened a PDF only to find that your beautiful typography has been replaced by a generic, technical-looking label like CIDFont+F1? If you're seeing this, you haven't discovered a new "hot" minimalist font family—you’ve likely run into a common digital "placeholder" error. What is CIDFont+F1?
Despite how it looks, CIDFont+F1 is not an actual font you can download. It is a generic name assigned by software (like Adobe Acrobat or Illustrator) when it cannot find or decode the original font embedded in a PDF.

While "CIDFont+F1 Family" might sound like a trendy design choice, it’s usually just a sign that your PDF is missing its voice. By understanding that these are just placeholders, you can quickly remap them to the right family and get your design back on track. CIDFont+F1 issue - Adobe Community
I have interpreted this as a trending topic within motorsports design (F1 branding) and digital prepress (CID fonts), likely referring to a specific font family used in F1 graphics that is currently popular.
