Apple Watch Series 7 stuck in boot loop, force restart not working

I have the series 7 did an update on it. It’s currently stuck in a boot loop. Battery still charges just gets warm. Force restart doesn’t work and it’s no longer listed as a watch in the iPhone app. Tried all the hacks to fix it, had luck with putting it in the freezer and it would boot up normally once it warmed up. I would be able to put my pin in and it would for properly for about a minute. Then it would turn off and be stuck in a boot loop again. Anyone have any ideas on how to fix it. Apple said it would cost a few hundred to diagnose it but it would cost only another hundred to get a new one.
