as explained in the thread title, I've that error if I try to unlock my 1password X beta extension on my Chrome browser (80.0.3987.162, 64-bit). I can reproduce the issue 100% of times. There are no issues if I first unlock my desktop app and then use the Chrome extension.
EDIT: I've just been able to reproduce the issue from Chrome extension even if the Desktop app was open, unlocked and active.
