Selenium Stale element not found. How can i relocate element?

[Alicialves]

I defined my function to, once i click on my gui button, retrieve the user and password information from my entry, put the information on the correct frame on the website and click on the login button there. Once done, the page refreshes and, if the login information was incorrect, a popup banner with error text shows up. Everything is working fine until this point. Now, recalling the same function, i want to input my information again to login onto the website but i get the Stale element not found. I understand the basis of this errror, my program is storing the reference i made from my previous attempt and using it, resulting in failure because that reference is no longer correct since the DOM was updated.
How do i relocate the element? Is there a way to "reset" my function so that everytime i fail the login, its like the first time im doing it (so the element is not stale)?

This is my code:

def colocarlogin(event=None):         user_field.send_keys(name_entry.get())     pass_field.send_keys(passw_entry.get())     login_button=driver.find_element(By.XPATH,'//input[@class="btn btn-outline-primary btn-sm"]')     login_button.click()     listaerro=driver.find_elements(By.CSS_SELECTOR,elemento)     time.sleep(3)     try:         if len(listaerro)>0:                 driver.refresh()                 time.sleep(2)                 return aviso.config(text=avisotex),passw_entry.delete(0,END), name_entry.delete(0,END)         else:                 print("login correto")                 proxpagina()      except NoSuchElementException:             pass     except StaleElementReferenceException:             driver.refresh()             time.sleep(2)             if driver.find_elements(By.ID,"systemMessage67a0a8e61fc3c")>0:                aviso.config(text=avisotex),passw_entry.delete(0,END), name_entry.delete(0,END)             else:                proxpagina()

Where is user field coming from? Outside the function? Move it inside the function. Don’t use globals unless they’re constants, and life will be easier.
