Issues connecting email to Outlook and apple mail after password update this morning

This Morning, I received an email from Xfinity to update the password. I had noticed my mail had not loaded to my iPhone since that email came in. Once I updated the password, iPhone and Outlook keep saying password incorrect. I have logged in to the Xfinity account via web browser, so I know it's correct. When trying to go to the account and identity, I'm also getting an error message: A rendering error occurred: Cannot read properties of null (reading 'toLowerCase).

Anyone having the same problem? How do I solve this?
