If you’re new to diagnosing issues as a bug, an issue on your end, or a feature request, the RStudio Community is a great place to start with. So, welcome and thanks for taking the time to help out!
Sometimes it turns out the what at first seems like an RStudio bug is actually an issue with a package or R itself. This is a good place for us discuss to discuss the problem and try to figure out which it is. And, since we've already started the conversation, we can continue it here!
So, to start off, what happens when you try to update the packages in RStudio? And which versions of R and RStudio are you using? Also, have you had a chance to check out the troubleshooting guide for the IDE crashing? https://support.rstudio.com/hc/en-us/articles/200488498-Troubleshooting-Guide-Using-RStudio
That said—to directly answer your question, here’s how to report bugs: https://github.com/rstudio/rstudio/wiki/Writing-Good-Bug-Reports
As Andres notes, that’ll take you to our GitHub issues page, which is for issues specific to the RStudio IDE—both bugs and enhancement requests. If the problem you’ve encountered turns out to be due to a bug with RStudio, we can continue the conversation there.
