  You are not authorized to assign user group &3 to role &2, system &1
  Cause
  The error typically arises due to one of the following reasons:

  Role Restrictions: The role being modified may have restrictions that prevent certain user groups from being assigned to it.
  User Group Configuration: The user group itself may have specific settings or restrictions that limit who can assign it to roles.
  
  Solution
  To resolve this issue, you can take the following steps:
  
  
  Check User Authorizations:
  
  Review the authorizations assigned to the user who is trying to perform the action. Ensure that they have the necessary permissions to assign user groups to roles.
