After upgrading to 56.2.0 each time I send an email - with or without an attachment - I receive a large attachment error message as thus: The size of the message you are trying to send exceeds the global size limit (30000000 bytes) of the server. The message was not sent; reduce the message size and try again.

I have no emails pending. None in drafts.

usually that error message appears when the outgoing server (SMTP) has been configured not to use a password, but a password is required. Some SMTP server respond with a login type error. Others respond that the message is to large.
