Yahoo requires a different password when using an email client. This URL may assist: https://help.yahoo.com/kb/SLN15241.html

Yes, I've tried that. I used that app password generator when Yahoo introduced that requirement, but now I can't get back to it. The generate app password button doesn't appear on the Account Security screen.

I've tried removing the email account and re-adding, but it still fails with to connect.

When re-adding the account, did you let the New Account Wizard determine the server settings, or did you manually enter the server settings? Yahoo uses OAuth2 authentication, and I'd the New Account Wizard expect to chose that. With OAuth2 authentication you'll have to use the main account password. An app password wouldn't work.

Yes I used the New Account Wizard, which doesn't choose OAuth2, so I then went on to Configure Manually then Advanced Config to change it to OAuth2, but it still says the IMAP server does not support the authentication method. So I've hit a brick wall. I don't understand how I could set it up initially, what has changed and why I can't re-set it up. Thanks for your help

At times, reinstalling a fresh version of the app can resolve your receiving problems. Uninstall and reinstall the Yahoo Mail app on iOS. Uninstall and reinstall the Yahoo Mail app on Android.

Please post your Troubleshooting Information. At the top right of the Thunderbird window, click the menu button ≡, then select Help > Troubleshooting Information. Press the "Copy text to clipboard button" and paste the information into your reply.

Re-installing Thunderbird would just be a waste of time.

Here's my troubleshooting info:
