我正在撰写论文report class。我试图在每个部分后缩进第一段。
包括\usepackage{indentfirst}在序言中似乎只缩进章节标题后的第一段。它不会缩进紧接在章节之后的第一段。任何缩进章节后第一段的建议都会有所帮助。

破坏了几乎所有 latex 的节标题控制。只需删除 flushleft 环境即可。
除了将标题放在组内的特殊问题（这可以防止它影响组外的后续段落）之外，章节标题不应该在文档中以内联形式出现，而应该作为文档设计的一部分在文档类中指定，或者，如果不行，则在序言中指定。
如果想要让右侧章节标题不整齐，可以更改
\titleformat*{\section}{\large}
到
\titleformat*{\section}{\raggedright\large}
