Unable to use as passkey

I’m trying to use my Onlykey as a passkey with a Google Pixel 8 Pro.

It works fine when for password input, however when trying to use it as a passkey there is some strange behavior.

I follow the prompts for passkey setup, select use USB device, and the “Connect your key” pop-up appears. The device then becomes unresponsive and the LED stays green. Sometimes I can input the pin, but it fails to accept it. Eventually Google Play Services crashes.

Has anyone else encountered this issue? The same behavior is exhibited with both DUO and regular Onlykey.

This Google issue for Yubikey describes the issue I am having. It says the workaround is to disable the Yubi-OTP interface.

Does anyone know how this relates to Onlykey?
