Apple Watch Ultra unresponsive and stuck on spinning dial

I’ve had this Apple Watch for about a year and a half before it it decided to act up. Place on charger overnight, unlock it, before I can walk into the next room it’s stuck on a spinning dial. Attempted to power it off, nothing, then tried to reset it from my iPhone, it no longer is connected to my iPhone, and watch is completely unresponsive. Had to use power and crown on the watch to turn it off. Comes on after some time, but no phone calls or text coming through or going out. Reset it from the watch which was also unresponsive and took several attempts. I have reset it more than a dozen times, set up as a new watch (no backup being used). Works for a moment and back to Same issue. Sent into Apple 3 times, they cannot duplicate the issue and finally sent a replacement, worked for a little over a day until I put on charger for more than an hour; unlock and back to spinning dial again before I could walk into the next room, and no longer connected to my iPhone again. I don’t know what could be causing this as the watch and phone have been updated to latest OS even when it was still iOS 17 and watch OS 10 (currently iOS 18.0.1 on iPhone 14 Pro max; 11 on Apple Watch Ultra 1) I would go with it being the phone if it weren’t for the fact I broke the back glass and just had the entire guts of the phone replaced before receiving the replacement watch. The agent at the repair desk mentioned this is a recurring issue they have with the ultra watch and have seen this on numerous occasions with other customers, is this something anyone else is experiencing? Is this a situation where I should give up on Apple Watch completely? Is there a solution? Information or suggestions would be appreciated.
