Resources must be listed in the web_accessible_resources manifest key

Recently started getting this error in chrome from the Avast Online Security browser extension

Denying load of chrome-extension://gomekmidlodglbbmalcneegieacbdmki/client/gpcWindowSetting.js. Resources must be listed in the web_accessible_resources manifest key in order to be loaded by pages outside the extension.

Without devtools open when loading the page, the errors seen are different (still in the Avast Online Security browser extension)
