Answer 1

The page you try to automate contains two similar forms, hence there are two elements within the DOM that match your XPath. The first one is not displayed and thus not interactable. That is why you got ElementNotInteractableException, and that is why you get TimeoutException trying to wait until it became visible.
Changing your xpath to "(//input[#name='username'])[2]" should solve the problem.

Answer 2

You can also try with the below xpath. It worked for me.
"//*[#id=\"load_form\"]/fieldset[6]/input"
