The Editor becomes unresponsive when generating lighting after changing the Minimum Probe Spacing value



Reproduction steps:
1. Open the attached “repro-project“
2. Open the Assets/Scenes/Colosseum_A/Colosseum_A.unity scene
3. Open the “Probe Volumes“ tab of the Window->Rendering->Lighting window
4. Under the “Probe Placement“ section change the Minimum Probe Spacing value to 0.5
5. Click “Generate Lighting“

Expected result: The Editor successfully generates lighting
Actual result: The Editor becomes unresponsive

Reproducible with: 2023.2.0a21
Could not test with: 2021.3.28f1, 2022.3.4f1, 2023.1.2f1 (Could not downgrade the project)

Reproduced on: Windows 10 Pro


This bug seems like a collection of different issues:
1. The Editor crashes in some Physics code on BV4_ProcessStreamSwizzledNoOrderQ<`anonymous namespace'::LeafFunction_BoxOverlapCB,OBBParamsCB>when performing the steps using Unity 2023.2.0a15
2. The Editor.log file is spammed with the following errors when running out of GPU memory while baking with the GPU lightmapper:
OpenCL Error: 'getNormalsFromLastBounceAndDoValidity.EnqueueNDRangeKernel(params.openCLState, 1, NULL, global_work_size, NULL, 0, NULL, NULL)' returned -4 (CL_MEM_OBJECT_ALLOCATION_FAILURE)!
OpenCL Error. Falling back to CPU lightmapper. Error callback from context: CL_MEM_OBJECT_ALLOCATION_FAILURE error executing CL_COMMAND_NDRANGE_KERNEL on NVIDIA GeForce RTX 3050 Ti Laptop GPU (Device 0).
OpenCL Error: 'processEmissiveFromBounce.EnqueueNDRangeKernel(params.openCLState, 1, NULL, global_work_size, NULL, 0, NULL, NULL)' returned -4 (CL_MEM_OBJECT_ALLOCATION_FAILURE)!

3. In Editor-prev.log for a stack trace from the physics system crashing
