New installation failed

[martin-settle]

I just installed the Mailchimp integration extension (CiviCRM 5.77.0 on Wordpress 6.6.2.

Installation seemed to go fine, but when I try to access the Mailchimp settings I get an error message. Thanks in advance for any guidance or help someone could give me. Here is the relevant section from the log file:
