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

I'm on an M1 Pro Mac running latest Tahoe 26.4 and latest MonitorControl

1 - Monitor Control app icon completely disappeared from menu bar.
2 - The display sliders on MacOS menu are greyed out and unusable
3- When using the brightness keys on keyboard, they take several hits to react. When it does, it does change the brightness but because the sliders don't work, you don't know at what point of brightness you are within the range.

What happend?

Steps to reproduce

Look up for app icon on macos menu bar. It isn't there.

Got to MacOS sliders menu control where display is. Sliders are greyed out and won't react to clicking.

Expected behavior

I expect the app's icon to be on menu bar as before

I expect display sliders to be fully functional

Anything else?

No response

Environment Information (please complete the following information)

- macOS version: Tahoe 26.4
- Mac model: Macbook M1 Pro 32Gb
- MonitorControl version: Latest
- Monitor(s):  Samsung s27R35x and Asus PA27JCV (the app was working great with both of these)

Hi there - can you make sure you download the latest app version from the GitHub site? If you are using an older app version, it might not report an update available for the latest version.
