Cannot sign in to 1Password WebApp via Edge Browser

When I want to sign in to 1Password's WebApp via Edge Browser on Windows there is an Error Message saying: "Anmeldung nicht möglich. TypeError: Cannot read properties of undefined (reading 'dsecret')"

I don't know how to fix this. Logging in to the Windows App, iOS App and Edge-Extension works fine. Even logging in with the Chrome Browser (which I don't use anymore) works. What is the problem here?

1Password Version: 8.8.0
Extension Version: 2.3.7
OS Version: Windows 10
Browser:_ Edge
