Crash when capturing attribute spreadsheet of Niagara GPU Particle with raytracing enabled

Crash when capturing attribute spreadsheet of Niagara GPU Particle with raytracing enabled

UDN
Description

Also, NiagaraDebugger crashes the moment I enable GPU Particle Readback.

Steps to Reproduce

Attribute Spreadsheet Repro

  1. Open the attached sample project
  2. Open the "SampleEmitter" asset and capture it in the attribute spreadsheet

Result: Editor crashes

NiagaraDebugger + GPUReadback Repro

  1. Open the attached sample project
  2. Create a Niagara System using SampleEmitter
  3. Place the System in the level
  4. Open the NiagaraDebugger
    1. Enable System Filter, set to *
    2. Enable Show Particle Attributes
    3. Add an entry to Particle Attributes, set to "Color"
    4. Enable Gpu Particle Readback

Result: Editor crashes
