  Remove Data: If possible, remove or clear the data from the structure. This can often be done through the relevant data management tools or by executing a data deletion process.
  
  
  Change Visibility: Once the data has been cleared, attempt to change the visibility of the structure again.
  
  
  Repopulate Data: After successfully changing the visibility, you can then repopulate the structure with the necessary data.
  
  
  Review Dependencies: Ensure that there are no dependencies or references to the structure that might be affected by the visibility change.
