Your Android App Bundle is signed with the wrong key

Can you please find below error and advise how to solve it. Also note, recently i have update one old watch face with new version of WFS because of wear OS new guidelines of August 31. And while uploading to play console it shows below error.
" Your Android App Bundle is signed with the wrong key. Ensure that your App Bundle is signed with the correct signing key and try again. Your App Bundle is expected to be signed with the certificate with fingerprint:"
Please advise.

This happens if you had an older app that was created with WFS it didn’t enforce the Play Store requirements or play store changed them

A valid password can contain 6 to 30 characters, begin with an alphabetic character, and use only alphanumeric characters and special characters like Underscore (_), Dollar ($), Pound (#). The password must contain at least one number. See Oracle’s Documentation

If that isn’t it let me know. I think the Play Store will work with you on it but I don’t remember how it was resolved.
