Infrequent WaitingTask->IsCompleted crash related to FNiagaraSubmixListener closing QAGame -game

Infrequent WaitingTask->IsCompleted crash related to FNiagaraSubmixListener closing QAGame -game

Description

Infrequent WaitingTask->IsCompleted crash related to FNiagaraSubmixListener closing QAGame -game

Unsure if related to [Link Removed] it was spawned from a group of oodle crashes and this is distinct enough

Steps to Reproduce
  1. Sync & Build QAGame
  2. Build and Open Unreal Insights
  3. Open a command prompt & run Engine\Binaries\Win64\UnrealEditor.exe QAGame QA-Promotion -game -tracehost=localhost -log
    • I found I was able to reproduce this more often when multiple copies were running (original hit this testing a verification related to profiling two sessions on one machine)
  4. Let run 2-3 minutes
  5. "~" to open the command console
  6. "quit"

Result:
Infrequent crash - 

Assertion failed: WaitingTask->IsCompleted() [File:F:\UE5_Release-5.0\Engine\Source\Runtime\Core\Public\Tasks\TaskPrivate.h] [Line: 365]

Expected:
No crash
