Building PDFs: net::ERR_ABORTED

I'm having trouble building PDF slides.

• Ubuntu 22.04
• R 4.2
• Tried multiple files, same error
• It works first time on my colleagues' laptops; except they are using Ubuntu 20.04
• Not sure what else to provide (I know, vague bug, sorry)

❯ xaringanBuilder::build_pdf("chapter1.Rmd")
✔ Building chapter1.Rmd into chapter1.html ... done
✖ Building chapter1.html into chapter1.pdf ... failed
Error in force(expr) :

Start by reproducing xaringanBuilder::build_pdf("chapter1.Rmd") on Ubuntu 22.04 and compare it with Ubuntu 20.04, then inspect xaringanBuilder/R/pdf.R around lines 92-98. Use the reported net::ERR_ABORTED failure and session information to narrow the PDF-generation step; done means PDF builds successfully on the affected environment or the incompatibility is clearly documented.
