Getting application error while accessing the rule. Unable to delete the corrupt rules from the system.
Reproducing the Issue
Please navigate to the corrupt rule under Configure Business Rules.
You'll receive an application error and rule definition will not load.
Please use Manage data admin tool to search "Rule" and then select corrupt rule from the drop down. (in case Rule object is not visible under manage data, you'll need to provide Role based permission under Rule object definition by enabling secure=Yes and then under Manage permission Role).
Take action and permanently delete record(s).
