将flextable渲染至Beamer演示文稿时出现编译错误求助

问题概况 #

我在用flextable生成的表格渲染到Beamer演示文稿时遇到问题：代码在Word、PDF、PPTX、HTML等格式下均可正常运行，仅Beamer格式出错；除flextable外，文本、图片、kable生成的表格都能正常编译到Beamer中。该问题在flextable的项目讨论中有相关提及。

可复现的示例代码 #

---
output:
  beamer_presentation: default
  pdf_document: default
  powerpoint_presentation: default
  ioslides_presentation: default
  word_document: default

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = FALSE)
library(flextable)

Slide #

example_ft <-
  iris |> head() |> 
  flextable()
example_ft

## 已尝试的调试操作
- 重新安装/更新R
- 重新安装/更新R Studio
- 重新安装/更新所有包
- 重启R会话
- 按照错误提示的LaTeX调试指南操作

我在三台电脑（2台Mac Pro、1台Dell）测试该Rmd文件，均出现相同错误。

我再次尝试上述调试步骤后问题仍未解决，希望能得到该问题的解决方案。
