Before opening the issue, have you...?

Searched for existing issues
Looked through the wiki
Updated MonitorControl to the latest version (if applicable)

Describe the bug

From time to time pressing standard brightness keys stops adjusting brightness. Nothing specific seems to lead to this behavior. Then, after some time, they return to their normal behavior.

Weirdly, when the keyboard brightness keys don't actually change the brightness, you can still change the brightness using the slider in the menu bar.

Steps to reproduce

Use your computer as normal
Brightness keys stop working
Wait for a couple of hours (I don't know the exact time, it's just an example)
It starts working again

Expected behavior

Brightness is adjustable using brightness keys at all times

Anything else?

No response

Environment Information (please complete the following information)

- MonitorControl version: 4.0.2 Build 6965
- Monitor(s): AOC U34G2G1

Might be useful as well: neither reconnecting and/or power cycling the monitor, nor restarting the program helped.

If you are using the built-in media keys then it might be that some other apps are interfering (like Karabiner etc)?

I'll convert this one into a discussion, maybe others have better suggestions about this one. :)
