I got exactly the same issue which started today. I launched Google Chrome and I got notified by ESET that something was attempting to modify Chrome, which never had happened with Chrome before, or at least not while I was opening it. So I told ESET to deny the changes, but it gave me a "Failed to read firewall configuration" error. It immediately started blocking Chrome, despite it having the necessary permissions to go through. I haven't tried any other filtering methods nor have I restarted my computer since. I disabled my firewall and chrome works as usual. It's the first time something like this happens to me, and seeing as it happened to other people on the same day, probably around the same time, I'm guessing it's not something I can easily fix without Google or ESET releasing some sort of update or patch.
Regardless, I'll try restarting my computer and switching filtering modes, although I doubt that'll help.
