If it worked before, and no changes have been made, the problem is probably external to thunderbird, such as an outage with the email provider. I have seen this twice today with other users.

Who is the mail provider?

You recently updated to version 148?

If so, pllease tell us, does something in https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo help?
