Problem:
When trying to run reports, view Service Domains Created, or view metrics created in a contract, I am getting an error on the UI: An internal error has occurred (2147023878). Error in t_log:
Illegal operation attempted on a registry key that has been marked for deletion.
Cause:
It seems that Windows is trying to access a registry key that actually does not exist. This is usually caused due to an environmental change that causes issues within the Windows operating system.
Resolution:
An example of a trigger to such an error is when a certain patch was applied on the server without restarting it. Please restart the server and check if the issue resolved.
Your IT department should be made aware of this
