Issue when launching shinystan demo

[anthonyhauser]

After having installed the shinystan 2.6.0 package in R 4.2.0, I tried to launch the model demo but the windows that should open pops and then quickly disappears, leaving the following message in the R console:

Listening on http://127.0.0.1:4995

3: shiny::runApp
2: launch

Here is my code:

install.packages("shinystan")
library(shinystan)
shinystan::launch_shinystan_demo()
