I'm trying to use passkeys to sign into my website from the app on my watch.
I get the following error in debug mode while being connected wirelessly:

There's one more hint:
03-05 22:56:08.781 9867 10507 I NullBinder: NullBinder for com.google.android.gms.auth.cryptauth.cryptauthservice.START triggering remote TransactionTooLargeException due to Service without Chimera impl, calling uid: 10172, calling pid: 11337
I get the popup where I can select my passkey, it even asks for my pattern, and then it fails.
The same goes for google sign in. I select my account, enter the pattern and then it fails.
So I'm using a physical device (Galaxy Watch 8 Classic) with the latest software. I have the android auth client in google cloud console with the correct debug hash. I also have the digital asset links file hosted under /.well-known/assetlinks.json.
