You should try to locate using cssSelector with it's attribute tabindex as below :-
#Cbk_List[tabindex='0']
Edited :- If checkbox element has not any attributes with unique value, you should try using xpath with index, assuming you want to get first checkbox element, then try below xpath :-
(.//*[#id = 'Cbk_List'])[1]
Note :- In above xpath, just change the index from 1 to desire one checkbox to find.
