1Password Safari Extension not showing up in Safari Preferences

I went to use 1Password in Safari today, as I do every day. I noticed the other day that the extension disabled itself and reappeared in a different part of the toolbar. Weird, but I didn't think much of it. Now, even after quitting and reopening 1Password (also quitting the helper services), restarting my Mac, and uninstalling the extension from my Mac and redownloading it from the App Store, it will not show up in Safari Preferences so I can turn it on. The button to open Safari Preferences in the little instruction window that appears when you "open" the extension also doesn't work. Maybe it's related.

1Password Version: 8.2.2 80202080
Extension Version: 2.1.3 (20182)
OS Version: macOS 11.6
