Uncaught EvalError: Refused to evaluate a string …

I’ve used duplicator for multiple sites some time ago.
Now I need to migrate website based on wordpress to different location.
I’m able to grab a copy, load to new server and … during the Test Databse following entry comes to console:

Uncaught EvalError: Refused to evaluate a string as JavaScript because ‘unsafe-eval’ is not an allowed source of script in the following Content Security Policy directive: “default-src ‘self’ http: https: data: blob: ‘unsafe-inline'”.
