Steps to reproduce:
1. Open attached Unity project from Google Drive link “LightingWindow.zip”
2. In docked Lighting window select “Adaptive Probe Volumes”
3. In Probe Invalidity Settings press on “Refresh Virtual Offset Debug” button
4. Observe the Console window

Actual results: “GUI Error” and “NullReferenceException” errors thrown in the Console window

Expected results: No errors are thrown in the Console window

Reproducible with versions: 6000.0.78f1, 6000.3.20f1, 6000.5.4f1, 6000.6.0b5, 6000.7.0a3

Tested on (OS): macOS Tahoe 26.5.1 (M1)
