We discovered one issue where Git-managed projects whose .git folder is not hidden for some reason can lead to slowness / hangs within RStudio (usually manifesting as extremely slow time for execution of commands in the console).
Executing that shows the files within the (project) directory, as well as hidden files in that directory. It's a way for me to see if this could be the culprit in the slowness observed (does a .git directory exist, and if so, is it hidden?)
