R session hangs up after using ggplotly()

Bắt đầu bằng cách tái hiện ví dụ ggplotly(viz, tooltip = c("text", "size")) được cung cấp trong một project và trong một session không có project, đồng thời ghi lại sessionInfo() và các package đã được nạp được hiển thị. So sánh hai môi trường và lần theo entry point của ggplotly(); công việc được xem là hoàn tất khi hiện tượng treo đã được tái hiện với nguyên nhân được xác nhận và một cách giải quyết đã được kiểm chứng.

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:
