Invalid path with leading 'null' on Windows 10

Latest version 23 creates invalid paths with leading null\ on Window 10.

I encountered this when updating SBT / coursier and dependencies where downloaded to a null dir inside my project.

Actual

import dev.dirs.ProjectDirectories
import $dep.`dev.dirs:directories:23`

ProjectDirectories.from("org", "scalameta", "metals")
// res0: ProjectDirectories = ProjectDirectories (Windows 10):
//   projectPath   = 'scalameta\metals'
//   cacheDir      = 'null\scalameta\metals\cache'
//   configDir     = 'null\scalameta\metals\config'
//   dataDir       = 'null\scalameta\metals\data'
//   dataLocalDir  = 'null\scalameta\metals\data'
//   preferenceDir = 'null\scalameta\metals\config'
//   runtimeDir    = 'null'

Expected

import dev.dirs.ProjectDirectories
import $dep.`dev.dirs:directories:22`

ProjectDirectories.from("org", "scalameta", "metals")
// res0: ProjectDirectories = ProjectDirectories (Windows 10):
//   projectPath   = 'scalameta\metals'
//   cacheDir      = 'C:\Users\user\AppData\Local\scalameta\metals\cache'
//   configDir     = 'C:\Users\user\AppData\Roaming\scalameta\metals\config'
//   dataDir       = 'C:\Users\user\AppData\Roaming\scalameta\metals\data'
//   dataLocalDir  = 'C:\Users\user\AppData\Local\scalameta\metals\data'
//   preferenceDir = 'C:\Users\user\AppData\Roaming\scalameta\metals\config'
//   runtimeDir    = 'null'

Environment

OS: Windows 10 1903 JVM: AdoptOpenJDK 1.8.0_222 / 1.8.0_282

Trying without -version 2 if Powershell fails sounds sensible to me but I would probably not check the error message because it is localized.

Btw, has somebody tried using JNA instead of shelling out to Powershell. Maybe that is easier than fighting Powershell.

Thanks @snlykf and @nartamonov for checking, and thanks to @phongngtuan for fixing it!

Closing this, let me know if you experience this again!
