I'm facing this issue ever since I upgraded to the latest version. Not sure when they'll release a fix but https://www.dropbox.com/s/10p6cjkenskcvqy/enable-1password-browser-integration.py?dl=0 is a https://www.raycast.com/ Script Command you can use for temporarily fixing the issue as you described and simplify the process without having to manually edit the JSON file. Just run the command called "Enable 1Password Browser Integration" whenever you restart 1Password app. Also make sure the directory where you save the script should be added under Raycast Script Commands as shown as in the screenshot.
Hopefully, the team releases a fix soon!
