[Yubikey 5 NFC] Error accessing FIDO application

[chrysle]

• YubiKey Manager (ykman) version: 5.5.1
• How was it installed?: via pip
• Operating system and version: ChromeOS, Debian 11 (bullseye) container
• YubiKey model and version: Yubikey 5 NFC
• Bug description summary: Access to FIDO application not possible

I connected my Yubikey to my chromebook, explicitly allowing for USB device passthrough, as required. Then I attempted to get a list of the SSH keys I have stored on the device. This has always worked on my native Debian system, beforehand. I ended up with the following error:

$ ykman --log-level DEBUG fido credentials list

I tried basically every other ykman command, also verified that the OpenPGP smartcard was detected and, all worked without issues.

I believe this is a duplicate of #464.

Thanks for the hint, I should have searched more thoroughly.
