[Bug] Hotkeys stop working after saving settings on Linux (HotKey already registered error)

[ZhBF]

Describe the bug
After saving settings (which presumably triggers a configuration reload), the global hotkeys stop responding. The logs indicate that the application is failing to re-register the hotkeys because they are considered "already registered."

To Reproduce

1. Start the application on Linux.
2. Verify that the global hotkey (e.g., Ctrl+Shift+D) works.
3. Open the Settings menu and click "Save" (even without changing anything).
4. Try to use the global hotkey again.
5. Issue: The hotkey no longer works.

Desktop (please complete the following information):

• OS: Debian GNU/Linux 13 (trixie) x86_64
• DE: KDE Plasma 6.3.6
• WM: KWin (X11)

Maybe the same issue like Windows before.
