Installation from store fails with ModuleNotFoundError

[JakePi3]

I've got logs at the end. I'm running Omarchy stable stream as the OS with Pipewire for the sound system and PulseAudio available as a compatibility layer.

When I install the plugin from the store, the installation "succeeds" but:

• No plugin settings can be accessed for this particular plugin
• No actions from the plugins can be added
• The plugin doesn't even show up in the list of available actions
• The plugin DOES show up as installed in the store
• I get a stack trace in the logs every startup as below
• Removing the plugin via the store does change its state in the store but it still attempts to load on startup

I've tried the following to fix:

• Set SDL_AUDIODRIVER=pulseaudio,alsa before installation.
• Tried installing a few sound libs via pacman but nothing worked so far

Since the plugin uses its own venv and I've looked inside to find pygame, my best guess is the module fails to load because its dependent on some library that's not available on my system but I can't identify what's missing.

Any help is appreciated.

Note that multiple plugin processes remain resident in memory (they seem to multiply until I exit the application). It looks like the module fails to load but there's no cleanup and the socket is never released.
