App may crash on wake from sleep or display connect/disconnect #1648

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

After sleep, then wake up when I press F1/F2 brightness just drops to like 0% and stopped to respond, no changes at all.
Have to restart app to make it work. Well, I mean any way of changing brightness is not working, with sliders for example.

Steps to reproduce

1. Sleep
2. Wake up
3. F1/F2

Expected behavior

Brightness should always work.

Anything else?
