crash when trying to add volume

[deathtrip]

i use arch linux and when i try to add a new volume or click preferences, i get a crash with the error:
System.ArgumentException: The drive name does not exist
Parameter name: driveName
[ERROR] FATAL UNHANDLED EXCEPTION: System.ArgumentException: The drive name does not exist

i tried compiling normally, then with --config=RELEASE, but it still crashes.
