Safari extension often loses connection to 1password

Something curious, though. I got a new Mac Studio, and was trying to figure out the best way to set it up. I made a Time Machine backup, but at first, I created a new user on the new machine, and then installed 1Password 8 and the separate Safari browser extension app up-front as part of bootstrapping the machine.

I didn't run into this issue for 2 whole days.

I have around 90% of my preferred app and system configurations saved as defaults write rules that I can just run on a new machine, reboot, and voila! But there are some new things post-Catalina that I haven't been able to track down defaults write rules for.

In the end, I ended up migrating my user profile over from my old machine via my Time Machine drive and Migration Assistant.app. Aside from having to deal with Homebrew x86 → Homebrew arm64 issues, I noticed that the browser extension timeout issue came back.

This leads me to believe that there is some file somewhere in ~/Library that is corrupted or needs to be reset in order to fix this.

I tried following https://support.1password.com/uninstall-1password/, but they haven't been updated for 1P8 yet. They also don't remove the iCloud data that 1P_Rob mentions in https://1password.community/discussion/126935/feature-request-secondary-1password-login.

I've also read https://support.1password.com/remove-1password-browser/, but they only cover the app and not the preferences, so no bueno.
