1PW 8 - Safari Browser plugin "disappeared"

Hi, in 1password 8 I installed Safari plugin from Mac Appstore. I used that a few times and now it suddenly doesn't show as Safari extension any more, little Icon disappeared, not listed in settings as extension. But its installed according to AppStore and I can see that in Launchpad ... So I can't enable it :( What can I do? (Its a new MacBook M1 Pro)
