According to the traces, it is still a problem with the password:

You say, that "emacs -Q" is working for you. Could you please bisect
your init file, until you find the culprit config? The smallest one? And
could you pls show your guilty config then? I don't need the text of any
configured password, but how it is provided by auth-source.
