In latex when I force a newline in a caption with \\ it gives an error saying \Hy@tempa has an extra } runaway argument?

Output

The issue you're encountering is due to the way LaTeX handles captions and the `\\` command. When you use `\\` to force a newline in a caption, it can lead to problems, especially if you're using the `hyperref` package, which is likely the cause of the `\Hy@tempa` error. The `hyperref` package redefines many LaTeX commands to make them compatible with hyperlinks, and this can sometimes lead to conflicts with other packages or commands. To fix the issue, you can try one of the following solutions: 1. **Use `\newline` instead of `\\`**: 

1
\caption{This is a caption with a \newline forced newline.}
This should work without any issues. 2. **Use `\linebreak` instead of `\\`**: 
1
\caption{This is a caption with a \linebreak forced newline.}
This will also force a newline, but it's a more "LaTeX-way" of doing it. 3. **Use a `minipage` environment**: 
1
2
3
4
5
6
\caption{%
\begin{minipage}[t]{\textwidth}
This is a caption with a \\
forced newline.
\end{minipage}%
}
This will allow you to use `\\` to force a newline, but it will also introduce a new paragraph. 4. **Use the `caption` package**: 
1
2
3
\usepackage{caption}
...
\caption{This is a caption with a \\ forced newline.}
The `caption` package provides a more flexible way of handling captions and can help resolve issues like this. 5. **Load the `hyperref` package last**: 
1
2
\usepackage{...} % other packages
\usepackage{hyperref}
Make sure to load the `hyperref` package after all other packages, as it can sometimes resolve conflicts. If none of these solutions work, please provide a minimal working example (MWE) that reproduces the error, and I'll be happy to help you further.
