qt creator with no debug layout anymore

When starting debugging with Qt creator the debugging layout is lost
(this came with tumbelweed 25 June 2018, Qt creator 4.6.1)
THAT IS HELL ON EARTH!
Even when manually set Window->Views->Reset to default Layout the "debugger
bar" below the source code does not appear anymore.
Hint: when deleting .config/QtProject, start Qt (and forced to configure) it
works ONCE (layout appears). Close Qt creator. Start again - debugging layout
is lost.
I have installed manually older versions down to 4.5.2 - same behavior!!
(no problems on opensuse 15) So it must(?) be related to tumbleweed specific
... but what?
