Segmentation fault (core dumped) RStudio

Description of issue - I have installed R and RStudio on Linux Mint few months back, all went smooth. A month back RStudio stopped working. I can run R from command line. I have tried running some commands that I found in answers on similar questions on linux mint forum and stackoverflow, but no luck. I hope this might be helpful info:

What is being done when the error occurs? E.g. does this happen on start-up, or possibly this is the message that appears when RStudio crashes?

Have you seen the discussion below (see Kevin's comments and mingwandroid's Feb 12 comment)?
What version of RStudio are you on?
