- [x] The issue remains after disabling all other extensions and restarting Visual Studio Code.
- [?] The [FAQ](https://github.com/James-Yu/LaTeX-Workshop/wiki/FAQ) cannot address the issue. At the moment here in CN, I have no access to the FAQ Web page, I don't know why.

## Environment*
> _Please write exact version numbers instead of descriptors such as `latest`._
- Operating System: Arch Linux, Linux red 6.14.5-arch1-1-tom #1 SMP PREEMPT_DYNAMIC Fri, 09 May 2025 02:00:03 +0000 x86_64 GNU/Linux
- VSCodium: 1.100.03093 04db33e1a7fc01c8fcac2fb4d5bbadaa6413bd75 x64
- LaTeX Workshop Version: 10.9.1
- TeX Distribution Version: TeX Live 2025 / tlmgr:r74703 / tlshell:r74646

## The Issue*
> _Please briefly describe the issue you come across._
- The coloring of the brackets are mismatched with a content like:
```
\documentclass{article}
\begin{document}
\texttt{TEST ME \symbol{`\\}}
\end{document}
```

### Reproduction Steps
> _Please list out the steps to reproduce your bug. Include relevant environmental variables or any other configuration._
1. Check if the extension LaTeX Workshop is enabled,
2. Create a tex file with the following content:
```
\documentclass{article}
\begin{document}
\texttt{TEST ME \symbol{`\\}}
\end{document}
``` 
3. Disable (or uninstall) the extension LaTeX Workshop
4. The tex file's colored brackets are okay.

### Expected Behavior
> _What were you expecting to see? Include any relevant examples or documentation links._
- Opening and closing brackets should match within enabled extension.
