XR Interaction Simulator throws NullReferenceException errors in the Console when no hands are in XR Origin and multiple cameras are active

How to reproduce:
1. Open the attached "IN-145779_URP Test.zip" project
2. Open the "test" scene
3. Enter Play mode
4. Observe the Console

Actual result: "NullReferenceException: Object reference not set to an instance of an object" errors related to the XR Interaction Simulator are spammed into the console
Expected result: No errors appear in the console

Reproducible with: 3.5.0-pre.1 (6000.3.18f1), 3.6.0-pre.1 (6000.5.2f1)
Not reproducible with: 3.4.1 (6000.3.18f1)

Reproducible on: macOS 26.5, Windows 11
Not reproducible on: No other environments tested

• Disabling the “Main Camera” (at the top of the Hierarchy in the project) fixes the errors
