Ui Element No Longer Valid for find child


I am using find child under td element in for each loop. After executing first td element whenever the bot click back button and when it tries to click next td element I am getting the error.
When I tried to insert selector attribute in child element It’s throwing error.


Is TD a link? if so can you datascrape and take all the links into a dt and loop them(Navigate and Go Back). That way you won’t have selector issues.
