Cannnot open Rnw file after R update to 4.4.0 - (TypeError): Cannot read properties of undefined (reading `count`)


I recently upgraded to R version 4.4.0 (2024-04-24 ucrt) and also updated the R version in RStudio via the global options.

Since the update, I am unable to open Rnw (RSweave) files. When attempting to do so, I encounter the following error message:

So far, I have tried installing and updating all the relevant packages such as

Solution

  • I had the same issue with an older version of R, so it is definitely an RStudio problem.

    I installed the previous version from here: https://docs.posit.co/previous-versions/rstudio/

    I am sure there will be a patch quite soon and you can upgrade again to the newest version of RStudio.
