I am not able to reproduce on Ubuntu. Could you perhaps launch through the terminal and post the stack trace / exception here? You might have to turn on DEBUG level with the --log-level DEBUG flag at the end. We don't need the whole log, just the stack trace should be enough to help us understand what is going on.

Oh, I thought I pasted the stack trace in here already. I've stopped the pcscd service now and got this fresh stacktrace to paste:

My original provided screeenshot happened again exactly the same.

I am not able to reproduce on Ubuntu

Probably because you did not stop pcscd -- but it is also a testament that the socket may have automatically started it on that distro but doesn't do that on Archlinux. Here it does not start it on its own despite the existence of pcscd.socket --- but also, the GUI error does not accurately describe the issue to the user so it can be fixed manually.

To clarify, this seems to be a problem on fresh installs. Ever since I started pcscd myself, the socket seems to be doing its job correctly? But it still doesn't address that the GUI error it throws doesn't help troubleshoot / self-resolve in the slightest.

Thanks for the log!

I should have been more clear. I meant to say that I cannot reproduce the same error message that you get (Unmapped error: null __enter__) on my Ubuntu machine. I am stopping pcscd but when I press PIV I get the correct error message, which basically explains that it cannot connect to the YubiKey. Perhaps this is not an issue on Ubuntu but is an issue on Arch and/or other distros. I do agree that the GUI error is not that helpful. We will look into this. Thank you!

I appreciate your understanding of the issue and a desire to at least make it more clear for the UI.

Thanks
