Describe the bug

After updating to Sequoia, there is an issue.
First of all the app will not start after logging in.
Then, after I start it manually I can change the brightness of the secondary monitor.
However, if I change the brightness of the main built in display, the app crashes.
I am using an M2 14" Mac Pro.

Steps to reproduce

Update to Sequoia.
Start the app manually.
Change the brightness of the built-in display.

Expected behavior

The app should not crash.

Anything else?

No response
