Cannot register a passkey on galaxy/android phone

steps:
1) run chrome 108.0.539.128 on android 13
2) navigate to https://try-webauthn.appspot.com/
3) select discoverable cred "required" on the top left
4) click "register new credential" and receive an error "a user attempted to register an authenticator that contains one of the credentials already registered with the relying party". See short video.

I don't have any other creds registered, the screen shows empty list. Even if somehow there are creds/passkeys registered for /try-webauthn.appspot.com is there a way to clear these on Android device?

Thanks,
Aleksey
