  Refresh the Session: Sometimes, refreshing your session or logging out and back in can help clear any temporary locks or selections.
  Use Different Transaction: If you are in a specific transaction that does not allow changes, try using a different transaction or mode that permits modifications.
  Consult with Team: If you are working in a collaborative environment, check with your team members to see if someone else is using the same element.
