Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - magento/magento2-functional-testing-framework is locked to version 2.4.5 and an update of this package was not requested.
    - magento/magento2-functional-testing-framework 2.4.5 requires php 7.0.2||7.0.4||~7.0.6||~7.1.0||~7.2.0||~7.3.0 -> your php version (7.4.33) does not satisfy that requirement.

You can also try re-running composer require with an explicit version constraint, e.g. "composer require mailchimp/mc-magento2:*" to figure out if any version is installable, or "composer require mailchimp/mc-magento2:^2.1" if you know which you need.
