The issue is that our ADB is old. We have updated it for our next release.
In the meantime what you can try is copy your Android SDK's ADB where we deploy ours in temp folder.
Start it manually with adb devices connected and then start Graphite.
If you do not start it before Graphite it will be replaced by ours. Unfortunately it happens on every start of Graphite.
I hope this will work for you and sorry for that inconvenience.
