@Marcos Believe it or not, some of us are developers and running an insider preview is part of our job. I'm not running the fast-release mind you, but we are taxed with keeping ahead of issues that roll out in RTM, as are you. Don't write this off as "you're just running a beta, sorry". Yes, it's very likely you have no control over the situation if it is indeed a bug or problem introduced by Microsoft, but pushing off your customers by effectively telling them it's "their problem for running a beta" is a disgrace. Choose your language wisely. A simple, yes we know the build has issues, we're awaiting a resolution from Microsoft, and will keep you updated with an ETA would suffice.
Also, keep in mind I've run insider previews since they became a "thing" and had ESET for almost all of that time (~5 years I might say). This is the very first time ESET has had any breaking issues...
