@sgunhouse I deleted Opera and am using Brave. It doesn't happen with Brave. And it never happened with Google Chrome or MS Edge. What a coincidence that it only happens with Opera and that Bitdefender states that "Opera Is Using expired certificates".
As the image shows "opera.exe attempted to establish a connection relying on an expired certificate" but I am sure that it must be the extensions that I don't have in Opera that are causing the issue. I don't even like extensions.
Sometimes, no answer is better than a bad answer.
