[SoundWave ->GetPrecacheState] fatal crash in build w/Granular synth

Hi there I got a same issue…UE4.26.1.

For my build, it launches successfully at the first time after build, then granular synth just wouldnt load everytime I launch later.
I tried both

  1. adding all granular synth as instances to level bp
  2. adding a new granular actor to level, and also instanced by level bp
  3. adding an event, everytime I click R, the level restart all granular components
    and here comes the problem: teh restart works during the first launch, then it never works again. So I guess it would be a “quit game” issue(maybe granular and sound waves are not properly stopped after closing the game?).

So I tested the quit game in editor, then my whole editor crashed:
Assertion failed: IsValidLowLevel() [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/CoreUObject/Private/UObject/UObjectBase.cpp] [Line: 129]

I’m quite sure now it is Quit Game destroyed my actors…even in editor(though granular synth run smoothly in editor)
