Steps to reproduce:
1. Open the attached user's project "ReflectionProbeTest.zip"
2. Open "OutdoorScene.unity" scene
3. Go to Quality -> HDRP in the Project Settings
4. Ensure Realtime Raytracing is disabled in the rendering section of the HDRP Settings
5. Enter Play Mode
6. Notice there is no exceptions or asserts in the console log
7. Go back to the Quality -> HDRP section in the project settings
8. Enable Realtime Raytracing in the rendering section of the HDRP Settings
9. Notice assertions messages in the Console

Expected results: No assertion printed in the Console window
Actual results: Assertion error is printed in the console when Raytracing is enabled with higher than a 64 reflection probe limit value

Reproducible with: 2023.3.0a11, 6000.0.26f1, 6000.1.0a3
Not reproducible with: 2022.3.52f1, 2023.3.0a10

Testing Environment: Windows 11 23H2
Not reproducible on: no other environment tested

Notes:
-Assertion error:
Assertion failed UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)
-These assertions are occurring in line 173 in WorldLightManager.cs as the k_MaxCubeReflectionsOnScreen constant is set to 64 but the maximum reflections on screen can be as high as 128 and in this project it's set to 96
