Thank you for the reply. It does indeed sound like something is going wrong with macOS and how it handles the connection to the Apple Watch. Our developers are aware of an issue that sounds like the behaviour that you're describing and have filed a bug report with Apple. I'd encourage you to report the macOS authentication issue to Apple on your end as well so that they can investigate further.
If you use the Mac after it wakes from sleep for an hour or so (without letting it sleep again) does the ability to unlock 1Password using the Apple Watch eventually return?
