After updated the R and Rstudio to latest version, I even can not knit(default [knit] button) the default .rmd, both html and pdf. I updated the rmarkdown and any other packages but still not working.

In system(paste0("rmarkdown::render \"", input, "\"")) : 
  'rmarkdown::render' not found

    `rmarkdown::render` is not a system function. You should not be using `system()` to run it. That is R code. What exactly does the code you are trying to run look like? It's easier to help you if you include a simple [reproducible example](https://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example) with sample input and desired output that can be used to test and verify possible solutions. – MrFlick Jul 19 '21 at 07:28
  • Thank you for your comment! I just new a default rmd and run [knit] button like I always do.. It did well before I updated. – Menkot Jul 19 '21 at 07:32

I got this error right now because of a R version update. I solved it by updating tinytex.

install.packages("tinytex")
