Sorry about this. And is this for RStudio Workbench, or RStudio Server (the free server version), or the desktop version?
And were you given a "next steps" in your report?
Focusing just on the exit code, I think this error occurs when you're trying to execute something your machine for which your user isn't permitted to do. In the example below, this person needed to install RStudio as an admin on their particular machine. When they were R wasn't able to start.
