R session hangs up after using ggplotly()

My R session (within RStudio) hangs up after using ggplotly().
For testing, I use one of the examples of ?ggplotly. The example normally works ok once or twice, but the R session hangs up after several tries (in the example below, the 2nd run hung up the session). I cannot even close RStudio from within the GUI and have to use the System Monitor application to kill it.
This problem arises when I run the following code after I have loaded a given project, not if I start a R session with no project. However, the project does not load any data or package, so I do not know how to identify the problem.
This is what I specifically do:

Inizia riproducendo l’esempio fornito ggplotly(viz, tooltip = c("text", "size")) in un progetto e in una sessione senza progetto, registrando la sessionInfo() e i pacchetti caricati visualizzati. Confronta i due ambienti e traccia il punto di ingresso di ggplotly(); il lavoro è completato quando il blocco è stato riprodotto con una causa confermata e una soluzione verificata.
