%The first command sets the indentation to 0 and thus cancels paragraph indentation. The second command sets the height of the trailing blank line. This is done using the LaTeX measure ex. One ex corresponds to the height of a lowercase ‘x’ in the current font style. I use 1.3 because I want the height of a capital letter. The “plus 0.5ex minus 0.3ex” part tells LaTeX that it can increase the height with at most 0.5ex and decrease it with maximum 0.3ex to make a decent layout. This means that the minimal height of the blank line is 1ex and the maximum 1.8ex.

有错误输出：
答案1
错误是由\justifyheading行上未定义的命令引起的
\titleformat{\subsection}[hang]
{\normalfont \bfseries\justifyheading \raggedright
% \setlength\leftskip{0pt} \setlength\parfillskip{-\rightskip}
}{\thesubsection}{1em}{}
因此，您有 2 个选项来修复错误。
\justifyheading从上面一行删除；或取消和
