Windows LAN Files will not Open

I cannot open files in RStudio from my shared LAN directory through the GUI however I can open them from the terminal.

file.edit("~\somefile.R") works fine however using the interface (Control + O) does not, I get a dialog
"Access Denied".

I can move my R files to a local directory and then its fine.

Any thoughts as to why this is the case?

getwd() \\myserver/myname$/DATA/My Redirected Folders/My Documents/R

This has only started happening with Rstudio Version 1.2.1335, [R 3.4.3 x64]

Just to say that I have the same issue as @ [byronalbrecht].
Thanks
