Admin Page with Custom client not loading (Content Security Policy)

[tony-cook]

Deploying custom client successfully.
Issue is with the admin page, "Content Security Policy: The page’s settings blocked the loading of a resource at inline (“script-src”)." error shows in console and loads a blank page. Everything else is working fine including "npm run undeploy" to re-visit the admin page.

Console screenshot in Firefox:

Any help would be appreciated.
