Connect yahoo with outlook 2021

Hello,
I have spent hours trying to connect my yahoo mail account with outlook 2021.
I have all imap / pop settings right.
In 2020 I created a password app through yahoo.
It does not work.
It can also not be changed or managed in my yahoo account.
I can also not creare a new app password.
The system only says that 'this function is not availanble.
What can I do?

Klaus
