These 'inline' CSP violation errors are in most cases false positives. If you can post the contents of the env tab from the log, that will have some more details, but I’m fairly certain this is coming from an extension.
The vast majority of CSP report violations logged are false positives, and we will shortly turn off reporting by default, because it’s not very helpful. Your best bet in implementing CSP is to visit the site with a few different browsers (Safari, Chrome, Firefox, Edge, and note that IE11 doesn’t support CSP at all) and see if there are errors in the console log.
