Sorry I haven't had time to look at this yet, but it may be worth testing with https://github.com/wine-compholio/wine-staging/blob/master/patches/kernel32- Console_Handles/0001-kernel32-Invalid-console-handles-for-new-processes-a. patch
With the patch applied the launcher starts correctly. Does that mean this is a dupe of bug #36216?
