do anyone experience this error In R4.0

I used the command and got an error

ss <- comCreateObject('InternetExplorer.Application')

ss[['Visible']]

Error in ss[["Visible"]] : 
  object of type 'externalptr' is not subsettable

While in R3.6, the code is successfully performed. does R4.0 modify something in subsettable flag?

I appreciate your help.

This appears to be a function from rcom, which is a CRAN package. This support site is intended to help people with Bioconductor packages. You could try stackoverflow.com, or r-help@r-project.org, which are more suitable places for your query.
