File listing error when upgrading from Rstudio 1.1.463 to 1.2.1335 or 1.2.1578 when navigating to folder

I think we diagnosed this issue already previously:

Broken file paths in Rstudio 1.2

Thanks for the response. Sorry to say, but I can't think of a reason why this would be the case. Can you think of anything else (e.g. another area where you might be mutating environment variables as used by R / RStudio)?

You likely need to modify the HOME and / or R_USER environment variables, and remove the trailing slash.
