I encountered similar issues in this post when rendering a flextable in a Beamer presentation.
Surprisingly, it worked fine for all other document formats like Word, PDF, PPTX, and HTML, except for Beamer. And I can also knit everything to beamer (text, figure, tables by kable), except a flextable.
So the problem is only at knitting a felxtable to beamer presentation. Example codes:
---
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
```{r echo=FALSE, results='asis'}
example_ft <-
iris |> head() |>
flextable()
example_ft
```
Every attempt to debug the problem was unsuccessful, despite trying the following steps:
Unfortunately, the issue persists and the error message continues to appear.

I would appreciate it if you could give me any solution for this.

Every attempt to debug the problem was unsuccessful, despite trying the following steps:
Re-installing/Updating R. Re-installing/Updating R Studio. Re-installing/Updating all the packages. Restarting the R session. Following the debugging instructions provided in the error below.
I ran in to this same problem recently when I tried running my script on a new computer. I found the issue is related to versioning of the flextable package. I had been running 0.6.6 on my old computer and obviously updated to the latest version on the new machine. I "solved" the problem by copying the 0.6.6 version from my old machine to the new one. It's not the ideal solution, and it doesn't explain the cause of the problem, but it's holding me over for now.
I used packageVersion("flextable") to find my version, and .libPath() to learn where my packages were stored so I could replace new with old.
