Describe the bug

Hey
I use a Dell U2720Q connected to my M1 2020.
When I try to use my (magic) keyboard to adjust the brightness of my screens, the app crashes. (Just disappears from the menu bar, without any error or such). When I use the touchbar of my M1 it doesnt crash.
When I try to adjust the brightness of my laptop monitor in the app, it crashes. When I adjust the brightness of my monitor it doesnt crash.

Steps to reproduce

Open app, adjust brightness of laptop via app or keyboard it crashes.

Expected behavior

Use my keyboard to adjust brightness. Use the slider in the menu to adjust brightness of my laptop.

Anything else?

No response
