It's true it's caused by Citrix Workspace, but I finally found solution today to have Citrix Workspace and Control Center running together without any Windows reinstallation (suggested by Gigabyte support) nor BIOS reset:
- uninstall Citrix Workspace and bounce your Windows
- check if Control Center is launching, if not reinstall Control Center
- install back the Citrix Workspace, but right after installation go to Services in your Windows, find the service called "Citrix Workspace Advanced Service" stop it and disable in its properties.
Make sure you won't restart your OS before that, cause once restarted this service is installing/updating "Citrix enterprise browser" which seemed to be the root cause of the issue, at least my issue
It may happen, that you will finally have to update your Citrix Workspace but then the same procedure should work.
Please update this thread if you find any other tricks.
Have fun ;)
