escape key " esc" and Siri not working due to issue with Siri.app
As described in this topic 253332998 the "esc" key does not work, Siri neither, if the Siri.app process crashes in the background (noticeable because Siri cannot be started neither via shortcut nor via icon in menu bar or voice command).
When you restart or log out, or kill Siri.app process, Siri relaunches (and works again), also the ESC key starts working again.
I've been experiencing this on my macbook Air M1 and my macbook Pro 14" on both Monterey and Ventura OS.
It is important to report the case to Apple Support . Many people have exposed this problem in this and other forums, but few have opened the case and worked on it with Apple.
Pd.: You can also leave your Product Feedback - Apple although it will not help to find the problem.
