Since you didn't even say which of the numerous files there has the
qprocess-related code I've created a rather simplistic example app and
attached it. It just starts designer with an argument via startDetached.
If that does not work for you somethings broken in your Qt indeed, if it
works then adjust it to make it more similar to the real code until it
breaks and tell us which change broke it.

Note also that startDetached is a static member function of QProcess, so
calling it on an instance like in your original mail does not make any
sense.
