iPhone won't connect to Comcast email after iOS 18 Update

Since I upgraded to IOS 18 and iPhone 16pro, I can no longer connect to my Comcast.net email account via the mail app. I have tried removing the account and adding it back, but I always get "Mail sent no password, go to settings->apps->mail and enter a password". Great help, but I am already in the apps->mail adding the new account. I verified the password because I can login online just fine. This all started with IOS 18 upgrade. Any help will be appreciated. All other accounts (iCloud, gmail, etc) all work fine. I have verified all the settings and also looked at the help section for apple mail on Comcast's site. I don't see where there is any problem. It looks like mail is just not sending a password. It doesn't say wrong password, it reports mail did not send a password. Any Suggestions?
