YubiKeys not recognized

[auroraanna]

• YubiKey Manager version: 1.2.5
• How was it installed?: from nixpkgs
• Operating system and version: NixOS unstable with Linux 6.6.52
• YubiKey model and version: YubiKey 5C NFC firmware version 5.4.3
• Bug description summary: The program does does not recognize any of my two YubiKeys

Steps to reproduce

Execute ykman-gui, plug in YubiKey.

Expected result

The application allows for configuration of the YubiKey.

Actual results

"Insert your YubiKey", cli error message (is repeated):

"PyOtherSide error: Traceback (most recent call last):\n\n  File \"<string>\", line 1, in <module>\n\nNameError: name 'yubikey' is not defined\n"
qml: Function not found: 'yubikey.init' (Traceback (most recent call last):

  File "<string>", line 1, in <module>

NameError: name 'yubikey' is not defined
)

I think I noticed this at least 1-2 months ago, but only recently did I try to look deeper into this.

Details

• YubiKey Manager version: 1.2.5
• How was it installed?
  • From pacman
• Operating system and version: Manjaro Unstable (latest updates) with Linux kernel 6.10.14-1
• YubiKey model and version
  • YubiKey 5 NFC, firmware version 5.4.3
  • YubiKey 5C, firmware version 5.4.3
  • YubiKey 5C NFC, firmware version 5.7.1
  • YubiKey 5 Nano, firmware version 5.7.1
• Bug description summary
  • YubiKey Manager GUI program does does not recognize any of my YubiKeys.
  • However, running $ ykman info in a terminal emulator works, thus this indicates that my machine is able to recognize my YubiKey devices via the CLI, but not via the GUI.

Logs

This is the stdout from launching the YubiKey manager app in the terminal (and I indicate in the comment what sections seem to endlessly repeat until the program is closed):

$ ykman-gui

This contrasts with the latest stable of Pop!_OS (22.04 LTS, with latest system updates), which uses version 1.2.4 of YubiKey Manager, and still manages to open fine with no issues. All that I see when I launch the GUI application via a terminal emulator is the following (including after closing YubiKey Manager):

$ ykman-gui 
Got library name:  "/usr/lib/x86_64-linux-gnu/qt5/qml/io/thp/pyotherside/libpyothersideplugin.so"
