The Issue:
You launch the ControlUp Console and get a black screen.
After you wait the console opens empty without your configuration.
The Cause:
In the license you have specific number of admins allowed. Look in the license under Quantity. During the installation you defined AD Group for Authorized Users - who can login to ControlUp Console.
The number of users in the group is more than the number in the license file. You might have nested a group in the ControlUp AD Group, and in that group you have more users than defined in the license.
The Solution:
Make sure in the ControlUp Authorized AD Group, you define the same number of users defined in the license file under Quantity (of ControlUp admins).
