launchfornuke: QMenuBar issue on Mac OS

Is there an existing issue for this?

Current Behavior:

Reported by Hisu on Community Forums here.

A few months ago I started to setup ayon for my studio, and I found the same issue as dan when I have to launch nuke (and hiero) from a Mac (mac studio, M4 chipset).

I also can not launch the DCC from the terminal, so I tried to debug and I found something interesting, here is what I did:

I first launch the "Terminal main" and then execute the command to launch Nuke (16.0v7).
Then from Nuke's Script Editor I execute the menu.py script in order to have Ayon in the menu:

from ayon_core.pipeline import install_host
from ayon_nuke.api import NukeHost

host = NukeHost()
install_host(host)

I get this error:

Traceback (most recent call last):
  File "<string>", line 6, in <module>
  File "/Volumes/.../ayon/ayon-core/client/ayon_core/pipeline/context_tools.py", line 136, in install_host

    assert len(menubar) == 1, "Error, could not find menu bar!"
           ^^^^^^^^^^^^^^^^^
AssertionError: Error, could not find menu bar!

It seems like it's a specific Qt issue in MacOS only, with menubars.

ayon-core/client/ayon_core/vendor/python/scriptsmenu/launchfornuke.py

Lines 16 to 21 in de3971e

	nuke_window = _nuke_main_window()
	menubar = [i for i in nuke_window.children()
	if isinstance(i, QtWidgets.QMenuBar)]
	assert len(menubar) == 1, "Error, could not find menu bar!"
	return menubar[0]

nuke_window.children() can't find any QMenuBar in Mac.
I add before the assert this:

if not menubar:
    menubar = [nuke_window.menuBar()]

then I can finally open Nuke from the launcher! (I also add the fix in ayon-hiero)

I don't know if this solution is the best but I hope this can help you !

Cheers
