Thank you for reporting this issue.
After an investigation it appears that this error will appear if the path uses a directory junction.
This error has been lowered to a warning in a future release (not necessarily the next release).

ye, i use a symbolic link, so what can I do? just use another directory?

hi @absollute64 .
in Windows File Explorer create
C:\Users\Owner\Documents\UnrealProjects

This works for my UEFN there is no space between Unreal Projects because you will need double quotes around the whole path, really messing up UEFN/Fortnite

thank you =)

The ‘fix’ has raised error for me now…
My published project has a different name than the one saved on my computer, so I get the mentioned error now since they do not match. Unable to launch a session, unable to push an update to my map.
The given error: “VersePath field ‘/localhost/{Local map name}’ of uplugin file ‘C:/Users/…/Fortnite Projects/{Local name}/Plugins//.uplugin’ is expected to match project Verse path ‘/questbox@fortnite.com/{Published map name}’”
