Broken LaTeX snippet

[Silzinc]

Hello! I have tried this on a rather simple installation (the docker version of LazyVim with their TeX extra). There are two snippets for begin, one of them is builtin, the other (the friendly-snippets one) is broken:

Failed to parse snippet
/usr/share/nvim/runtime/lua/vim/lsp/_snippet_grammar.lua:178: snippet parsing failes
```tex
\\begin{${1:env}}
  ${1/(enumerate|itemize|list)|(description)|(.*)/${1:+\item }${2:+\item[] }${3:+}/}$0
\\end{${1:env}}
```

I guess this is made for inserting an \item automatically when the $1 is itemize, list or enumerate. But for now it just crashes :/ Also, if it is repaired, is it possible to remove the builtin one which just has less capabilities? I don't know how to do that. Thanks in advance if someone can solve this!

I'm facing the same problem, there are two kinds of latex snippets.

You can check it on ~/.local/share/nvim/lazy/friendly-snippets/snippets, there is a latex folder that contains: bibtex.json, latex-snippets.json and vscode-latex-snippets.json. And there is a file called latex.json not in the latex folder.

The file latex.json has the code snippets like BEQ - Begin Equation, the problem is: for some reason, its set up to paste the current text that is in your yanked register.
You can see this opening the file and in the body of the snippet you'll find
"body": "\begin{equation}\n\t${0:${TM_SELECTED_TEXT}}\n\end{equation}",
and the TM_SELECTED_TEXT puts what you have yanked inside the \begin{equation} enviroment.

In the picture I've yanked 1 + 2, and when i type "beq" the code snippet will put the yanked text (1 + 2) inside the equation.
