Issue in shiny package in radiant

I am trying to host the Radiant app on the is successfully bundled by Renv and successfully Running on Local R studio.when I host on the cloud it is built successfully but it gives the Runtime error :

Error in library(shiny) : there is no package called ‘shiny’
I have checked renv lock file shiny package is already present in it

so why it's giving this error?

I have attached github link which contains the source code and some supporting messages and runtime logs.
