Niagara + audio component resulting in crash (5.2)

Programming & Scripting

I have a BP containing two Niagara systems (an orb and a vortex), and I’ve placed it in the world. I want the systems to respond to sound, and so for any changes to take place, I had to create a Niagara script module, but the engine crashes every time I hit start.

The problem persists until I delete the script module from the content browser (removing it only from the particle update list will still result in a crash). I deleted the script module, and recreated the patch via scratch module in the Particle Update section, and now I’m stuck in a loop where I cannot prevent the crash, even if I delete the scratch module.

Removing the culprit actor from the world yields the same results, unless I save the project. With or without adding audio to trigger the patch, the engine will still crash.

Note: the niagara systems work as intended until I create the script module (script model procedure was shown in tutorials; cross/double-checked for mistakes).
