Can't modify or disable "Custom Hardware Driver"

[PeteClubSeven]

Hi, unfortunately I've run into an awkward problem where I can't set a correct HWI or revert it back to using the built in HWI. The issue seems to be that the "Apply" button is only enabled when you initially toggle "Custom HWI Driver" to its on state. If you turn it on, click "Apply" and then disable it, the "Apply" button disappears so you can never actually save your settings.

These are the use cases and how the app reactions:

• When "Custom HWI Driver" is off
  • Toggle "Custom HWI Driver" on: "Apply" button is visible and can be used to save your settings
• When "Custom HWI Driver" is on and you clicked the "Apply" button:
  • Toggle "Custom HWI Driver" off: "Apply" button disappears and can't be clicked so your settings are never saved
  • Modify the path field: The "Apply" button is never enabled so your settings are never saved

After saving an incorrect HWI path the app is in a broken state when trying to interact with USB signing devices.

I'm using Nunchuk v1.9.25 running on an M2 Mac Mini with macOS 14.2.1. I'm not logged into the app so I don't have multi-device sync turned on. I've tried deleting the following directories but every time I open the app it seems to remember my broken HWI path:

• ~/Library/Application Support/nunchuk
• ~/Library/Saved Application State/io.nunchuk.macos.savedState

Here's a screenshot of the error I get when trying to scan for a "wired key" when I disable "Custom HWI Driver"

I tried version 1.9.20 and it seems like the issue is because this confirmation was removed when disabling "Custom HWI Driver"

It's worth noting that when modifying the HWI path in 1.9.20 the "Apply" button is never enabled however when you click a different option or return to the main menu you are shown the same prompt as above.

I tried 1.9.28 and this is still an issue :(
