I'm at a bit of a loss here, when I try to run Obok DeDRM from the officially sourced install, it fails to find the necessary userkeys for the desktop app. However, if I run Obok using the install sourced from pacman, it works as it should. I'm currently running CachyOS(Arch) Linux, and I also have a second partition with Linux Bazzite where Obok functions normally from the official install.

So far I've tried: Installing the same version thats available on pacman(8.7), using an isolated install, uninstalling the pacman version but leaving the dependencies before installing the official binary, running the install of Calibre I have installed on a different OS partition, and installing a different version of Obok. None of it works other than running Calibre from pacman and I'm not sure whats so different that makes the plugin unhappy.

Here are some outputs from the terminal:

Calibre 8.15

Code:
