How to revert to the previous interface?

After rebooting, suddenly my headset started speaking on its own and the menu became disgusting, inconvenient. I bought a certain item knowing what it was, but in the end it changed without my consent. It seemed like I was finally starting to get out of depression, but here, too, everything had to be ruined for me. That Activision does not want to admit its mistakes and does not offer solutions (it just banned my accounts and my friends', simply because Windows is installed on ReFS). This is similar harassment of the user here.
