Missing Dropdown menus

App has loaded without issue but only shows SMART SHOOTER 5 in top Menu bar with a dropdown of - Services/Hide/show/quit. None of the other menus (File, Edit etc) or Main window with Camera controls/ live view/preview etc are opening. I have downloaded to another computer and it works fine. Both are Mac OS.

I have Lightroom loaded on both desktops with no problems tethering etc.

I’ve run out of ideas…Jacqueline
