I'm getting this same error. I've looked in the _main.log file and found these error messages that are more descriptive.

Potential 1: `Package biblatex Warning: Using fall-back BibTeX(8) backend: (biblatex) functionality may be reduced/unavailable.

)`

Potential 2: Package biblatex Warning: Language 'latin' not supported. (biblatex) Using dummy definitions on input line 262.

Potential 3: `Package biblatex Info: Trying to load bibliographic data... Package biblatex Info: ... file '_main.bbl' not found. No file _main.bbl. Package biblatex Info: Reference section=0 on input line 262. Package biblatex Info: Reference segment=0 on input line 262. Runaway argument? {\scantokens { \LARGE {\bfseries {\@title }} ! Paragraph ended before \MT@prot@l was complete.

\par l.315 ` To me, this looks like an encoding problem. Something somewhere has not specified UTF-8. To fix this, I tried to set the backend argument in the index.rmd file to bibtex8 like so: `use-biblatex: true bib-latex-options: "style=authoryear, sorting=nyt, backend=bibtex8, maxcitenames=2, useprefix, doi=true, isbn=false, uniquename=false"` This didn't work. I'll try again later, or maybe someone else can take this and run with it.

Thanks a lot, @camcmac!

Changing from biblatex to natbib did not fix the problem either. The error message is the same.

Is this problem related to this one: https://github.com/yihui/tinytex/issues/347#issue-1073730171?

Indeed, adding \microtypesetup{nopatch=item} and \microtypesetup{patch=item} to templates.tex fixes the problem.
