I had the same issue after the update just now. Also, if I manually started up Monitor Control, it can change the brightness of the external monitor by dragging the slider. However, if I use keyboard shortcut or drag the slider over the macbook display, the app crashes.

Make sure you guys are using the latest app version (4.3.3). You might need to re-add the app to Login Items and set up Accessibility Permissions again.
