Why get the ERR_BLOCKED_BY_ADMINISTRATOR error?

When I visit the same page with Avast Secure Browser and Windows Edge, the result is not the same. Some elements can’t get with Avast Secure Browser, blocked by the next error:
“ERR_BLOCKED_BY_ADMINISTRATOR”

Example URL: https://www.matricesydeterminantes.com/determinante-de-una-matriz/

You can show the errors in inspector console and inspector sources tab.

Hi,

I would like to inform you that we have replicated the issue and will investigate furthermore to discover the cause. Thank you for reporting this.

Best regards,
