Chrome extension not communicating with 1Password app
The Chrome extension is completely non-functional on one iMac that I use. It always shows 1Password as being locked, regardless of the lock state of the 1Password app. Clicking on the extension icon shows me the dialog with only one button, labelled "Open 1Password". Clicking that button has no effect. I have made sure that the extension's option to integrate with the 1Password app is turned on. 1Password integration does work in Safari, which is not the browser I use (please do not waste my time by suggesting that I use Safari instead of Chrome; this is merely useful debug info).
I have tried completely uninstalling both Chrome and 1Password, rebooting the OS, restarting the 1Password Extension Helper, removing the Chrome extension and installing the beta version instead, and tried out the 1Password Troubleshooting utility (where I tried clicking the "re-enable 1Password Extension Helper" button). None of these things has had any effect on the problem. Several other mac OS computers I use have no such problem with the Chrome extension communicating with 1Password.
I'm out of ideas, and am considering resorting to wiping and reinstalling the OS from scratch, but that would be a huge time sink. First I'm trying the OS update to 11.6, but I have no expectation that will help.
1Password Version: 7.8.7
Extension Version: 2.0.7 (also 2.1.0 beta)
OS Version: 11.5.2
