I'm getting the exact same error with Mailchimp v2.2.5 on Drupal 10.4.7.
In addition /admin/config/services/mailchimp returns the message:
The website encountered an unexpected error. Try again later.

Did you use composer to install Mailchimp and have the v3 library of thinkshout/mailchimp-api-php in your vendor directory?
