GPD Controller emulation: Changing to "Paused" mode breaks HHD functionality

[fsworld009]

In Steam game mode, if I changed GPD Controller from any emulation mode to "Paused", the HHD would break:

1. Steam is no longer paused
2. Buttons and left stick controller control the steam menu, not HHD UI
3. Controller shortcuts registered in HHD no longer works.

I've tried sudo systemctl restart hhd@$(whoami) but it doesn't fix the issue, the only way to fix it is to reboot.

Steps to reproduce:

1. Enter Steam game mode
2. Open HHD
3. Go to Controller page
4. Change Controller Emulation from the current Emulation mode to "Paused" mode.
   • Note: If it's currently in Paused mode, the bug can also be triggered by switching to any emulation mode, then switch back to "Paused" mode.

Log when switching to "Paused" mode:

❯ journalctl -u hhd.service -f

Jan 01 14:40:26 fsw9-m2 hhd[1208]: GPDW   INFO     Removed rule '95-hhd-devhide-045e-028e.rules'.

(I don't see any related log when switching to emulation mode.)
