I have the same error message on stock Arch Linux with Yubioath Desktop 5.1.0-3 from repos with my Yubikey 5C NFC.

Though I haven't tried running the app via doas (am not using sudo).

Thanks for the report! The line WARNING: PC/SC not available. Smart card protocols will not function. indicates that pcscd is not running. Can you make sure it is?

[AtjonTV]

I can confirm that it worked normally after starting the pcscd service manually.
