What's Wrong?

OS: Windows 11 (Version 25H2)
Claude Code Version: 2.1.39

I'm using the Dev Drive feature on windows to mount a .vhdx as the primary drive for my source code. Claude is unable to recognize that the jetbrains ide and it have the same directory open.

My working directory is E:\source\repos\notification-service and in the list of running IDE's it's picking up the opened directory in Rider as /mnt/e/source/repos/ntification-service

What Should Happen?

Claude should correctly detect that it is currently open in the same directory as my IDE.
