FireStick 4k MAX

I’ve just updated on all my FIrestick’s and have a problem on just 1, my Firestick 4k MAX. The select button registers (Click sound from TV) when I click it but nothing happens. I have two remote on that TV and bot behave the same. My iPhone fire app is able to select. But everything in the UI That requires the select/ok (Center button) does not work with this new release.
What I’ve tried:
Cleared data/cache/reinstall app,
Updated firestick
Power cycled everything.

Clearly the Select/OK mapping is wrong on the Firestick 4K Max remotes.

Same for me. Is the only option to sideload an older version?
