Cannot display mapview output after installing R 4.0.0

After I installed the R 4.0.0, I cannot display the mapview output in the viewer of RStudio. It would be great if someone can give me some hints to solve this.

Here is an example code.

library(mapview)

mapview(breweries)

And here is a screenshot of my RStudio Viewer. There is no error message, but the viewer is just blank.

enter image description here

Here is my session information, and I am using RStudio Version 1.1.442.

Solution to problem:

I have just installed R Version 4.4.0 and upgraded Rstudio to v 2024.04.0 build 735. I was suddenly unable to use MapView with the same symptoms as described above. The Viewer pane just came up blank. This was also true for trying to display the widget produced by ggplotly in the plotly package.

Just by fluke I discovered by putting the command

options(viewer = NULL)

before the mapview command solved the issue.

For the example above, try:

library(mapview)
options(viewer = NULL)
mapview(breweries)

This seems to be an issue of some combinations of RStudio, R and leaflet versions on Windows, see these GitHub issues:

Try to upgrade your RStudio, maybe it'll help (at least they say it's fixed for RStudio v1.3.957-1).
