Cannot republish my R/Shiny app

I have been updating and republishing an R/Shiny program on Shinyio every month for years. This month when I tried to do it I received the message: "Publishing content requires an updated version of the rsconnect package. Do you want to install this package now?" I clicked yes and the installation was done successfully. However, I still cannot republish. Every time I try, I get the same message telling me I must reinstall rsconnect. What is my problem?
