The following code doesn't throw an error for me with LaTeX2e
<2023-11-01> patch level 1:

--8<---------------cut here---------------start------------->8---
\documentclass{article}

\begin{document}

\noindent \{x\}\\
\textbraceleft x\textbraceright

\end{document}

%%% End:
--8<---------------cut here---------------end--------------->8---
