Could you properly format your post using code blocks for code and terminal outputs? Thanks.
If your code contains code blocks, you need to enclose it using more backticks, i.e., usually four ````.

Could you share a small self-contained "working" (reproducible) example to work with, i.e., a complete Quarto document or a Git repository? The goal is to make it as easy as possible for us to recreate your problem so that we can fix it: please help us help you! Thanks.

---

You can share a self-contained "working" (reproducible) Quarto document using the following syntax, i.e., using more backticks than you have in your document (usually four ````).
See https://quarto.org/bug-reports.html#small-is-beautiful-aim-for-a-single-document-with-10-lines.

If you have multiple files (and if it is absolutely required to have multiple files), please share as a Git repository.

Additionally and if not already given, please share the output of quarto check within a code blocks (i.e., using three backticks ```txt), see https://quarto.org/bug-reports.html#check.

A reproducible example, or at least some information on your document content is needed here as this type of error is directly related to LaTeX and not Quarto. So usually directly link with the document content or configuration you used.

Here is a wild guess based on last time I encountered this error:

• peerj_article knitting error: Command \gather already defined rstudio/rticles#513

It came from lineo package, that was required to be loaded after amsmath, but they fixed it lineo version 5.1.

To thing to get from this that could help:

• If slightly related, be sure to update you tools and adapt the latex code
• If not related, this shows problem can come from deep layer in the tools used, so without more information, it is hard.

We need you to help us help you. thanks
