Issue/Introduction

The definition of rules using Access Groups on its conditions is causing performance degradation on the Groups administration.

STEPS TO REPRODUCE: 

1. In the Modern UX, select Administration => Blueprints.

2. Create four new Blueprints.

2. For each new Blueprint, edit the Blueprint and add a Rule.

3. Create the Rule on each Blueprint as follows
On the Conditions, select Access Groups.
Use the operator (equals or not equals)
Select a list of Groups (use eight different groups)
Select Action => Hide Modules.
Hide the Financial Plans.

4. So, there are four new Blueprints, each of them having a Rule using Access Groups on its condition.
The rule is just hiding a Module.
 
5. Now, on the classic UI go to Administration => Groups.

6. Try to do some task like creating a new group, deleting a group, activating a group or deactivating a group.
 
Expected Results: The action (new/activate/deactivate/delete) of the group is performend on the expected time.
Actual Results: The action is taking too long to complete, making the administration of the groups imposible.
