Resolution
WORKAROUND
Remove any references from registry variables that refer to other registry variables.
To find invalid references, search for a "Reference to registry variable"
or disable all of the rules associated to the domain (tab) such as Oracle, and then reenable the rules in groups until the problematic rule can be identified.
Then edit the rule
Change the Global Default from a reference to a Static Value
For example from this
To this
Then click Finish to save the changes
