I got the same problem it is blocked now at the bottom.
These errors appear:
Failed to load resource: net::ERR_BLOCKED_BY_CLIENT
/wp-content/plugins/cookies-and-content-security-policy/css/cookies-and-content-security-policy.min.css?ver=2.24
/wp-content/plugins/cookies-and-content-security-policy/js/js.cookie.min.js?ver=2.24
/wp-content/plugins/cookies-and-content-security-policy/js/cookies-and-content-security-policy.min.js?ver=2.24
Also this error:
Uncaught ReferenceError: Cookies is not defined
at cookies-and-content-security-policy-error-message.js:1:608
Update
At the moment I am investigating and trying out options, ADDING these three resources to the plugin’s whitelist did not solve my error unfortunatly.
