Error clicking button with selenium

[julio2000]

time.sleep(5)
driver.find_element_by_css_selector('.js-checkout-step-submit').click()
time.sleep(0.4)

This above is just a piece of my code with.

When I run this with the other code I've written it gives this error:
selenium.common.exceptions.ElementNotInteractableException: Message: element not interactable


I am pretty sure the path ('.js-checkout-step-submit') to the button I want selenium to click is right because I found is right. Cause I used SelectorGadget to find it wich worked well for me before.

Does someone have an idea what is going on or could someone maybe help me?
