apa 和 cedilla 重音字符错误：\B@my@dummy 定义中的参数编号非法

Question

我使用的theapa是参考书目样式。如果其中一个参考文献的作者在字符下带有变音符（即{\c e}在作者姓名中产生带有变音符的 e），我会得到编译时出现以下错误（具体来说，由 Overleaf 制作）：

Illegal parameter number in definition of \B@my@dummy.
    
<to be read again> 
                   \crcr 
l.11 \cite{Waledzik_2011_Multigame}
                                   
You meant to type ## instead of #, right?
Or maybe a } was forgotten somewhere earlier, and things
are all screwed up? I'm going to assume that you meant ##.

这参赛号码布文件中规定References.bib如下：

@inproceedings{Waledzik_2011_Multigame,
    title           = "Multigame Playing by Means of {UCT} Enhanced with Automatically Generated Evaluation Functions",
    author          = "K. Wal{\c e}dzik and J. Ma{\'n}dziuk",
    booktitle       = "Artificial General Intelligence: 4th International Conference",
    volume          = "6830",
    series          = "Lecture Notes in Computer Science",
    pages           = "327--332",
    publisher       = "Springer",
    year            = "2011"
}

.tex 文件的完整代码：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{theapa}

\title{Test}

\begin{document}

\maketitle

\cite{Waledzik_2011_Multigame}

\bibliography{References}
\bibliographystyle{theapa}

\end{document}
