Passkey in Salesforce (Heroku) not working

Hi,
1Password Beta seems to break Salesforce (Heroku) 2FA login and registration.

When I try to login to Heroku using the built-in fingerprint scanner as 2FA, Chrome won't ask me to "Use passkey", but simply freezes. I managed to login with 2FA by disabling the 1Password Chrome extension.
I tried to register 1Password as both "Security key" and "Build-in authenticator", but both freeze similarly to the login.
The background is darkened when trying to login or register 1Password, thus the problem might be after the website has triggered the Passkey registration / login flow. There were no output in the Chrome JavaScript console.

I am happy to provide more information.

1Password Version: 8.10.8
Extension Version: 2.12.0
OS Version: macOS 13.4
Browser:_ Chrome
