Performance issues with 1Password for Mac 8.10.78 (desktop app)

I'm adding to this to avoid creating a new thread on what seems to be related. Mac OS 15.5 1Password 8.10.78, on various M series Macs. The app itself is incredibly slow. Even typing in any field takes a few seconds to appear, and there is a definite lag in any action whatsoever. Typing a large string of characters freezes the 1PW app. I had to remove the extension in Safari because it was making the browser so slow, it was unusable. Further, the small 1PW icon (Safari) in any field appeared to be dead. Clicking on it fails to do anything. The issue does not seem to be present in either Edge or Firefox, both of which extensions are working fine and without delays, although the actual app on the Mac desktop itself remains practically unworkable.
