I'm running RStudio 1.3.1073 on Ubuntu 18.04 LTS and I'm also finding that RStudio immediately crashes on startup. I've uninstalled (as well as purged all config settings), reinstalled, and restarted multiple times and it's still happening.
I was Googling to see whether anyone else was encountering this, and whether anyone had found a fix, but I just found this post, so that makes at least two of us.
Best,
Jeremy
