为什么我添加带有受保护引文的脚注后 pdfLatex 编译会失败？

Question

我最近开始学习 LaTeX，因为它非常漂亮。虽然我的文档看起来很漂亮，但我的代码却丑陋不堪。我在 Windows 10 上使用 Kile，并使用带有 BibteX 后端的 BiblateX（在 biber 不起作用后放弃了使用它的想法；我尝试了这里建议的所有方法）。

事情是这样的；我在脚注中添加了另一个参考书目条目（之前有 8 个，甚至在另一个脚注中添加了一个，它工作正常），pdfLatex 给出错误“已完成，退出代码为 1”。在解决这个问题一段时间后，发现如果我抑制它\printbibliography（通过添加%），它又可以正常工作，甚至在脚注中打印正确的引文编号 [9]。我使用序列pdfLaTex>BibTex>pdfLaTex。我无法弄清楚哪里出了问题，甚至不知道问题出在哪里（脚注？引文？\printbibliography命令？还是文件.bib？）

这是我的 MWE；

\documentclass{book}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{textcomp}
\usepackage{courier}
\usepackage[bottom]{footmisc}
\usepackage{xcolor,xfrac,lmodern,graphicx,mathtools}
\usepackage{etoolbox,fancyhdr,float,wrapfig,amsmath}
\everymath{\displaystyle}
\apptocmd{\thebibliography}{\csname phantomsection\endcsname\addcontentsline{toc}{chapter}{\bibname}}{}{}
\graphicspath{{images/}}
\usepackage[font={rm,footnotesize,sl,color={darkgray}},labelfont={bf,color=black}]{caption}
\usepackage[font={rm,footnotesize,it}]{subcaption}
 \usepackage[a4paper,width=150mm,top=25mm,bottom=25mm]{geometry}
 \usepackage[style=nature,sorting=none,bibencoding=ascii,backend=bibtex]{biblatex}
 \addbibresource{refer.bib}
 \usepackage[nottoc]{tocbibind}
 \setlength{\parskip}{1em}
 \renewcommand{\thefootnote}{\alph{footnote}}
 \emergencystretch=1em
 \pagestyle{plain}
 \begin{document}
 \frontmatter 
\tableofcontents
\mainmatter
This is a test sentence.
\footnote{Obviously fake footnote.\protect\cite{tape}}
\renewcommand\bibname{References}
\printbibliography[heading=bibintoc]
\end{document}

我将不胜感激任何帮助。为了简洁起见，我添加了 refer.bib 文件的四个条目。我刚刚注意到前三个 @Article 条目显示为蓝色，而其余的条目显示为红色。这是什么意思？

@Article{g,
