This has happened to me twice, each of the past two updates for my Galaxy Watch 4. Each time, whether I initiate from the phone or the watch, it downloads the update and fails trying to copy that data to the other device.
The fix is:
1 - Put the watch on Wi-Fi and connect to a network
2 - Put your phone in airplane mode
3 - From the watch, search for updates and apply
4 - The watch will skip trying to copy data to your phone since it can't talk to it in airplane mode, and it should apply the update directly
5 - After it has rebooted, let the watch finish updating, then take your phone off airplane mode. Open the Wear app and check for updates. It might need to scan but it should show your watch as fully updated.
Was on chat with Samsung support for an hour before I figured this out. They wanted me to ship the watch back for "repairs".
Hope this helps someone else.
