I am able to recreate this issue and will be looking into it soon (hopefully tomorrow). Thank you for the bug report! And for the details/image, it's extremely helpful :smile:

I was running into the same issue with a different setup, perhaps it helps to track down the error. My workstation is windows with an installation of msys2 and mingw64 in it, since I needed the PATH variable from msys to start atom because of atom/atom#12608. The output of $PATH in mingw64 shell is

└─> $ echo $PATH

/mingw64/bin:/usr/local/bin:/usr/bin:/bin:/c/Windows/System32:/c/Windows:/c/Windows/System32/Wbem:/c/Windows/System32/WindowsPowerShell/v1.0/:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl:/home/user/.gem/ruby/2.3.0/bin:/c/Progra\ Files/7-Zip/

The error message caught inside atom after the same procedure described by @dk0r is

/C:/Users/user/AppData/Local/Temp/atom/.atom/packages/quantum-shell/lib/quantum-shell-controller.coffee:393

In my setup c is mounted on /c/... and not /C:/ so the different handling of paths in linux and windows is probably causing the issue since the regex expression has to be different.
