Hi, from the error message it appears that the Google Maps API configuration is incorrect. Found similar error in https://stackoverflow.com/questions/61294093/google-maps-api-error-this-api-key-is-not-authorized-to-use-this-service-or-api
Typically, this error is caused because Enabled API in your Project settings doesn’t work for embedded maps.
Try to enable Maps Embed API and it should work.
