1Password not loading at start-up

I still have this problem although I am on 1Password 8.50 (iMac Intel i3; Sequoia 15.1), At startup as soon as 1Password appears on the Menu Bar (and icon jumping in dock), the Mac slows to a halt and the coloured wheel of death starts spinning for >3-5 mins. Right click on 1Password icon shows "app not responding". Nothing else will appear in Menu bar until 1Password finishes what ever it is doing. Force quit and restart 21Password will eventually work but whole process takes ~8-10 mins to get Mac started...!
