更新软件包后，图像无法通过 bookdown 呈现

Question

我正在使用 bookdown 和 RStudio 创建 pdf 书。使用 更新 latex 包后tinytex::tlmgr_update()，图像突然不再渲染，无论是使用knitr::include_graphics()还是\includegraphics{}，但图形标题仍在渲染。

它看起来是这样的：

请注意，在我更新所有 latex 包（和 tlmgr）之前，一切都运行正常，因此路径或代码文本没有任何变化。我尝试卸载tinytex所有包，然后重新安装，但似乎仍然遇到同样的问题。

bookdown 创建的文件.tex包含以下内容：

\begin{figure}
\includegraphics[width=0.9\linewidth]{images/test} \caption{\label{fig:test}Test figure}\label{fig:unnamed-chunk-1}
\end{figure}

最小工作示例：

--- 
title: "Test book"
date: "`r Sys.Date()`"
site: bookdown::bookdown_site
documentclass: book
output:
  bookdown::pdf_book:
    latex_engine: xelatex
    fig_caption: yes
    citation_package: natbib
    includes:
      in_header: preamble.tex
link-citations: yes
keep_md: true
keep_tex: true
---

# Test book

Test figure:

```{r, fig.cap="\\label{fig:test}Test figure", echo=FALSE, message=FALSE, out.width="90%"}
knitr::include_graphics("images/test.png")```

前言：

\usepackage{booktabs}
