iPhone 12 and series 8 watch stuck in pairing updatel oop

I have an iPhone 12 and a series 8 Apple Watch and it’s getting stuck in the updating loop. It has previously been synced with this phone. I went in and made sure in the settings to delete all previous information about the watch and previous up dates and backups. I deleted the whole watch app and re-downloaded it. I’ve made sure to hard reset the watch. I reset the network settings I tried the Bluetooth trick where you turn off the Bluetooth while it’s downloading. I’ve tried using different Wi-Fi. I’ve tried turning off my cellular data. I don’t know what to do.
