Cmd+\ autofill not working in Chrome

I had to reinstall Chrome for MacOS to fix a newly appearing "something went wrong with your profile" issue. In the process of reinstalling, of course, I reinstalled the 1Password Chrome extension.

I visited a website with a password and hit Command+. Nothing.

The password box had a 1Password icon and a "please click here to autofill via 1Password" message. Okay, fine. I accessed 1Password. It asked me for my password, I entered it, and it popped up the full 1Password page with a "would you like to autofill the credentials for this website?" offer. I said no and hit Escape to clear the 1Password window.

I was still looking at the same web page, so I hit Command+. Nothing.

I checked the Google Chrome Extensions tab - yep, 1Password is installed and running.

I checked the 1Password main app - yep, it's currently unlocked.

I checked the 1Password extension permissions - yep, it's permitted to access all sites.

I checked 1Password to make sure it's the latest version - yep, dated today, all good.

I checked Chrome it see if it's up-to-date - yes, no updates needed.

Maybe it needs to refresh. I hit Command-Q to quit Chrome and restarted it.

I revisited the same web page and hit Command+. Nothing.

This is so tiresome. Why can't 1Password reliably do the one thing that it's supposed to do?
