tvOS 17.5.1 breaks TV volume control over IR

I have a latest Apple TV 4K that worked perfectly for so long but after I updated it to 17.5.1 it no longer controls volume over IR. I checked with a special tool and my Siri Remote just does not send any IR signals anymore unlike a regular remote from the TV set. At the same time when I press a volume up or volume down or mute button - Apple TV blinks so it does receive the command over Bluetooth.

Please fix asap - it’s really annoying
