Describe the bug

Hi, first of all thank you for your hard work. I have been using this for a long time.

After updating to macOS Sequoia, the monitor control app is no longer working for the MacBook Air M1 built-in display.

If I try to manipulate the brightness of my built-in display, (either from the keyboard shortcut or the slider in the menu bar), the app just "crashes" (it closes itself) without changing the brightness.

Weird thing, it does work with my external monitor (LG 32 UN550).

Steps to reproduce

Open the monitor control app
Either click on the icon on the menu bar and slide the brightness for the built-in retina display
The app closes itself and the brightness remains the same

Expected behavior

The app manages the brightness as it was before (please 🥹)

Anything else?

No response

Environment Information (please complete the following information)

- macOS version: 15.0 Sequoia 
- Mac model: Macbook Air M1 (2020)
- MonitorControl version: Version 4.2.0 build 7048
- Monitor(s): LG 32 UN550 (working), Built-in Retina display (Not working)
- Apple Silicon/M1 (yes or no): yes

I have the same issue with M1 MacBook Pro and Dell UltraSharp monitor. App closes/crashes immediately when trying to adjust the brightness on the built-in display (via UI or hotkeys), but adjusting the brightness on the Dell works.
