follow the path in the warning and grab that log file, post it here and then we can all see exactly whats going on 
C:\Users\micka\AppData\Roaming\Unreal Engine\AutomationTool\Logs\C+Program+Files+Epic+Games+UE_4.22\
put the Log.txt into google drive and then right click it and click “Get shareable link” then post that link here.
also have a look at that file yourself, down the bottom it will list all the errors it had and you might spot something that you know how to fix (its the best way to learn cooking errors)
