shiny app deployed in 2018 on shinyapps.io not working locally in 2019

I worked on a historical slavery map shiny app project during 2018 period.

My shiny app whas deployed on shinyapps.io with success. You can have a look to my project here

Today, I want to upgrade my app but unfortunately the UI is not working locally (white screen, no modal window, etc...here)

I download my app bundle from Shinyapps.io to use packrat and isolated packages versions used in 2018 without sucess. It's not clear to me how to do this. In Rstudio in Packages > Packrat > Options project > local repositories field. Do I have to indicate the path of the packrat folder of the bundle?

Here are the packages used in the map

library(shiny)
library(shinyWidgets)
library(leaflet)
library(dplyr)
library(dygraphs)
library(DT)
library(readr)
library(shinyjs)
library(shinyBS)
library(htmltools)
library(bsplus)
library(leaflet.extras)
library(dplyr)
library(tidyr)
library(readxl)

My shinyapps bundle tar is on my github here
