save_kable does not work after installing R v4.0.2 - r

Question

I have successfully used save_kable() from kableExtra to export latex tables into *.png before. However, after updating R to the version 4.0.2, save_kable always ends with R fatal error (no specific error message is shown, the session is just aborted). I installed a clean version o R 3.6.3 and everything works fine again.
Next, I re-installed MikTEX, but this does not seem to be the problem because R Markdown can knit a .pdf file without an issue (in the 4.0.2 version). Also, using save_kable with "html" options works fine and exports the table into .png. The problem seems to be specific for latex.
Looking at sessionInfo(), the only difference is that R 3.6.3 automatically loads the 'magick' package, while R 4.0.2 does not. However, loading the magick package manually in the latter R version does not solve the problem. Then, of course, the sessions differ in the "compiler" package versions. Maybe this is the source of the problem?
Any help would be much appreciated. The problem can be reproduced with minimal code such as
kable(mtcars, "latex") %>% save_kable("test.png")

Answer 1

This seems to be a windows specific problem. I actually just asked a recent question here
kableExtra HTML styling in Rmarkdown and kable_save()
Some of the things I have seen mentioned as potential fixes are listed there such as updating ghostscript, not using tinytext, updating some latex packages including 'standalone', and editing the policy.xls document in ImageMagick ImageMagick security policy 'PDF' blocking conversion.
None of these worked for me and I get the same crashing issues the second I try to kable_save a latex format into png. However, some other Windows users have found success with the steps above so maybe try that out and see how it goes.
