Users are unable to create projects when the default project location is a networked drive

Description

There have been multiple reports of this issue, particularly from schools, over the last 10 years:

From a recent user's report:

Setting project path so that every time a user starts Unreal Engine the project path is set to N:\ and the failed to process config file error is corrected.

I believe this could be because Unreal Engine isn’t liking the redirected profile path to the document drive. On our environment we have Desktop and Documents folder redirected to a Distributed File Server share path. It is a UNC e.g. \\bcotac.local\StudentData\2024\%USERNAME%\Documents. 

Unreal Engine Editor doesn’t like the redirected Documents path which is a UNC path. There is a work around but we have to manually browse. I have gone through forums and reddit posts and haven’t been able to find a variable that can be set on the configuration .ini files to set a default project path that would work. 

We would like to set this on the system environment variables for all the PCs in our Art & Media so students wouldn’t have hassle of browsing manually to the Home Folder Drive. 

Screenshot 1: When students open Unreal Engine and try to create a project the path it picks up is the UNC path to the Student’s Document drive or the home folder which is mapped to N:\

Screenshot 2: We then manually change it to N:\ by typing it and when creating the project it comes up with the following error

Screenshot 3: It only works if we browse for the location and select the redirected Documents folder that is mapped to N:
Steps to Reproduce

Repro 1:

  1. Launch the engine
  2. In the Unreal Project Browser window enter the full path to your network drive as Project location
  3. Observe the "Folder Path is not valid" prompt

Repro 2:

  1. Launch the engine
  2. In the Unreal Project Browser window enter the file path with the letter assigned to your network drive as Project location
  3. Observe the "Failed to process file {ConfigFile}" prompt

Actual result: The project cannot be created if the file path to the network drive is not selected through the browse for a folder icon.

Expected result: The project can be created without needing manually select the file path through the browse for a folder icon.
