A day later and still no response, but coincidentally a newer version of 1Password for Safari was released in the last day, so I installed that --- so now running 2.5.1 -- but there is not much different happening. The release notes for this new update refer to now-fixed problems with the extension unexpectedly locking itself. So I was hopeful that updating the extension would fix my issue. The one small difference that I notice is that, now, when I launch the browser, the 1Password iconic the browser's toolbar initially shows itself in unlocked state (no lock symbol on 1Password icon in browser's toolbar). Soon enough, though, and faster than I can click on it, the lock icon is rendered on the toolbar button. Today, even after successfully updating to version 2.5.1, I uninstalled the extension and then reinstalled it. Unfortunately, no change in behavior: it's still un-openable on Safari Technical Preview but works fine on standard Safari.
I would sure appreciate some thoughts
