CAN Devices Not Detected When Executable Is Run

### Describe the bug

Hi,

I'm using your application to forward messages between CAN buses, and I've noticed an issue when running the executable file. When I call the detect_available_configs function, it does not detect any CAN devices. However, when I run the Python script directly, the CAN devices are detected without any problems.

### To Reproduce

### Expected behavior
