How to reproduce:
1. Open the attached “IN-120762” project
2. Open the “SmokeStack_Dark” VFX Graph
3. Wait for ~10 to 15 minutes
4. Observe the crash

Reproducible with: 6000.0.60f1, 6000.2.6f2
Could not test with: 6000.0.44f1 (could not open the “SmokeStack_Dark” VFX Graph), 6000.2.10f1, 6000.3.0b8, 6000.4.0a3 (reproduction is inconsistent- see notes)

Reproduced on: Windows 11

Notes:

- Reproduction can be inconsistent ad/or take different amounts of time for the crash to occur
- The issue does not occur when the VFX Graph is undocked
