Error when exporting an abstract to PDF

I encounter this when trying to export an abstract to PDF. Do you know what might have happened and how to solve this? Many thanks.

LaTeXRuntimeException: LaTeX compilation of /opt/indico/tmp/indico-texgen-euw3ytlk/single_doc.tex failed

Check the log file in /opt/indico/tmp/indico-texgen-euw3ytlk/ for the actual error (ideally just share the log file here). If there’s nothing sensitive in the abstract (which I guess is indeed the case since you already shared the screenshot here) feel free to zip that whole folder and upload it here.

Note: It may have been deleted depending on how long ago the error happened. But you can simply try generating the PDF again and a new folder will be created.
