Siri not working in iphone 12 pro after upgrading to ios 14.6

I did upgrade my phone to ios 14.6 . Siri is not working. i pressed to trigger siri from Airpods pro, i pressed the phone power button to invoke siri, i tried the Apple watch also. All i can hear is that the first siri Triger sound. Siri is not responding and not even trying to listen to my instructions.

After the first try , even if i try to invoke siri again. It will not work. I changed the settings, but to no avail.
