Apple Mail Yahoo Login

Hi,

my Yahoo account was suddenly disconnected in Apple Mail and when I try to give in the login data Apple Mail crashes when entering the password.

I tried a lot of things, like restarting in the save modus, deleting files from the preferences, deleting the account from Mail, etc. Nothing worked. The other accounts I have in Mail work fine.

I have an old system (Mojave) but would like to ask if there is another chance what to do that could help.

Thanks
