Shiny app runApp error

I have a shiny app that ran perfectly on Friday. Now, when I press 'run app' or shinyApp(ui, server), I get this error:

Listening on http://127.0.0.1:5638
Error in .Call("rs_shinyviewer", url, getwd(), 3) :
Incorrect number of arguments (3), expecting 4 for 'rs_shinyviewer'

I get the same error when I run this skeleton shiny app:

library(shiny)
ui <- fluidPage()
server <- function(input, output, session) {}
shinyApp(ui, server)

This suggests it's a problem with the RStudio cloud shiny support. Help?
