System Settings crashes when clicking on Pen & Drawing

### What Happened?

_System Settings_ quits and dumps core when I go to _Pen & Drawing_.

### Steps to Reproduce

1. Open System Settings
2. Go to Pen & Drawing. It should crash when you click it.

### Expected Behavior

Later I found that deleting the cache folder at `~/.cache/io.elementary.settings/` makes it work, but only once; it crashes again after reopening _System Settings_.

The cache file at `~/.cache/io.elementary.settings/wacom/devices` contains this:
```
[056a:037a]
Styli=Generic;
```

And there is nothing else in that folder. The error message (see below) references a missing file/directory at `~/.cache/io.elementary.settings/wacom/tools`, and it's really not there.

Installed package versions:
- io.elementary.settings: `8.0.3~r1431+pkg88~ubuntu8.1`
- io.elementary.settings.wacom: `8.0.2+r453+pkg7~ubuntu24.04.1`

Journald logs a core dump, which you can find here (near the bottom): [journald.log](https://github.com/user-attachments/files/25213722/journald.log)

I'm also attaching the output of `G_MESSAGES_DEBUG=all io.elementary.settings`: [elementary-settings.log](https://github.com/user-attachments/files/25213938/elementary-settings.log)
