I'm getting a 'network name cannot be found' message when I to save R scripts to UNC paths within RStudio.
For example, when saving a script called deleteme.R containing the single line print('Hello World!') to UNC path \\my_host\my_share\my_project_directory\deleteme.R, I might get a message that says: "Error saving /my_host/my_share/my_project_directory/deleteme.R. The network name cannot be found".
This error does not occur when I try to save this same script from R (i.e. RGui).
It happens intermittently in RStudio, but frequently enough to be a real problem. The error started happening when I upgraded to RStudio version 2022.12 and continues to happen with version 2023.03.0 Build 386.
