Shotgun Desktop stalled at startup

Hello, I have the same issue on two different rigs running Centos 8, when I launch ToolKit it goes well, launching the GUI and I see modules being loaded until it starts to stall and gives me this feedback:

Thank you for help

I run 1.6.1-1

So it was related to gnome desktop. The SG Desktop was running but unable to display the icon. For now I switched to KDE, works as expected !
