After the disabling auto startup of winebus by changing
"Start"=dword:00000002
to
"Start"=dword:00000003
in its "WineBus" service entry in registry the problem disappears.

Since by default Scheduler service is disabled (and gets enabled only once
at least one task is being added) this regression was not noticed until now.
