Steps to reproduce:
1. Create a new Unity project using Universal 2D Template
2. Add attached “QAFreeformNRE.cs” script to project and add it to any GameObject in Hierarchy window
3. Enter Play Mode
4. Observe the Console window

Actual results: “NullReferenceException: Object reference not set to an instance of an object” error is thrown in the Console window

Expected results: no exception is thrown. The light gets a default shape, the way it does when the type is changed in the Inspector or created from GameObject > Light > Freeform Light 2

Reproducible with versions: 6000.0.84f1, 6000.3.25f1, 6000.6.4f1, 6000.7.0b3, 7000.0.0a1

Tested on (OS): macOS 27 (Apple Silicon)
