[Bug Report] Clicking Help button freezes UI

### Describe the bug:
In the UI Edit a rule. Click the Help button. The application freezes. Perhaps the Help button is trying to launch a browser and I have a block rule in place? Or it is trying to open a prompt to ask for permission?

Include the following information:
- OpenSnitch version: 1.6.9
- OS: Debian
- OS version: Trixie
- Window Manager: KDE Plasma Wayland
- Kernel version: 6.12

### To Reproduce:
In the UI Edit a rule. Click the Help button. The application freezes. I have to terminate the UI application.

### Post error logs:
opensnitch-ui console doesn't say much. Just when I terminate the app it says "Aborted (core dumped)"
```
Themes not available. Install qt-material if you want to change GUI's appearance: apt install python3-qt-material.

### Expected behavior (optional):
Application window should not freeze.
