I'm not sure if you have the same issue as I did, but my scripts stopped working after the most recent update. I realised an additional tab which didn't exist was being created and i had to switch the focus to the correct tab using:

driver.switch_to.window(handle)

You can check if you've got focus on the correct tab by printing driver.title and seeing if it has the same title as you expected. If it doesn't then just make sure to switch to the correct window before executing the rest of your code
