Code in \lstlisting breaks document (compile error)

Question

I want to show a JSON object in my document. If I do the following, it works:

\begin{lstlisting}
{
  "id": "5",
  "key": "discardedCard"
}
\end{lstlisting}

But if I extend the code to the following, then there are only errors when compiling the document:

\begin{lstlisting}
{
  "id": "5",
  "key": "discardedCard",
  "value": {
    "suit": "DIAMONDS",
    "rank": "QUEEN"
  }
}
\end{lstlisting}

Error log:

! Incomplete \iffalse; all text was ignored after line 19.
<inserted text> 
                \fi 
l.19     "
          suit": "DIAMONDS",
A forbidden control sequence occurred in skipped text.
This kind of error happens when you say `\if...' and forget
the matching `\fi'. I've inserted a `\fi'; this might work.

! Incomplete \iffalse; all text was ignored after line 19.

I'd like to provide a MWE but if I run the code in a MWE then it works. So it looks like there are other parts in my bachelor thesis which break the document.

Is there a way to output code in a listing in a secure way or maybe escaped?

I would guess you have a language shorthand (babel?) that defines " to do something, you can locally turn shorthands off, which might help
