Unable to pair my Apple Watch SE with any iPhone

hello i think i accidentally unpair and pair with the new phone with update. after the update i cant pair and keep stalling at install phase.

the update is 10.6.1 and i believe this is the last update for any se 1st gen. its really frustating, thinking the last

os update is the broken os, i cant even pair with any phone.

before u guys said hard reset or anyhing im doing most of the method none are these are working. i even send to apple to diagnose and the result is still the same. i wonder apple also cant handle this os problem. not even a hardware problem.

please if any here is one of the developer for watch os. pls update the latest os for one last update.
