We are using Rstudio on Desktop not desktop pro. When we attempt to update it to the latest version, we get an error : 'Cannot conect to R'. Additionally the 'Help' button is disabled, so we cannot generate a diagnotics report. We are seeking help to resolve this issue. Please find the attached screenshot for reference
It might help to know what operating system you are using and whether this is a standalone installation on a PC or involves a remote connection.
Also, if you open a terminal and run R (not RStudio), does R run properly?
