Recently I have been getting the following error whenever I close my Rstudio window:

The issue is not super pressing since I haven't had any issues while I am actually using RStudio but I thought I would mention it. When I first started getting the error I was using R 3.4.1 and RStudio 1.1.383. I updated my R version to 3.4.3 and uninstalled and reinstalled Rstudio and still got the error after each.
Here is the my output to sessionInfo():

And I get the error when I close my RStudio without having done anything except opening the app.
Any ideas why I am getting this error or how to resolve it?
