1. Open system settings.
2. Open Desktop Behavior.
3. In Desktop Effects Disable all the effects.
4. Go back to all settings.
5. Open Workspace Theme.
6. Switch to breeze Dark.
7. Go Back to all settings.
8. Open Desktop Behavior - > Desktop Effects.
9. Crash.

Note. After restarting application the crash happens again every time I visit firstly Workspace Theme and dont switch theme as far as I already had a bug and then I visit  Desktop Behavior - > Desktop Effects.

Reproducible always.
