First I would try to upgrade all dependencies of rmarkdown. Perhaps the easiest is to install pak and use pak to upgrade

install.packages("pak", repos = sprintf(
  "https://r-lib.github.io/p/pak/stable/%s/%s/%s",
  .Platform$pkgType,
  R.Version()$os,
  R.Version()$arch
))

(Cf. All about installing pak. — Installing pak • pak)

pak::pkg_install("rmarkdown", upgrade = TRUE)

Thank you Mr Gabor for all these but this is still not working. Now What i am thinking is uninstall both studio and R and use the lower version of R

Perhaps a foolish question, but do you have RTools for the current version installed?
