Error with Audio Capture Component


Whenever I add an audio capture component, and assign the same sub mix to a Niagara Script, I receive the below error message.

What is particularly interesting to me, is everything is installed at either E:\Epic Games\UE_5.0EA or the project is located at E:\Unreal Projects\InfiniteMatrixStarter 5.0 and the project is being built in E:\Unreal Projects\InfiniteMatrixStarter 5.0\Build

I found this error thread: Please help me Unable to package after updating Bridge

Which suggests that Quixel Bridge is the culprit… As I’m not currently using it, I see no reason not to disable it. But I still receive the same error.

This runs fine in the UE IDE when I press the play button.

I also found this error thread: UE5 fails to initialize. Assertion failed: IsValid() [File:D:/build/++UE5/Sync/Engine/Source/Runtime/Core/Private/Windows/WindowsPlatformFile.cpp] [Line: 602]

And have tried uninstalling and reinstalling UE multiple times.

Final interesting(?) note, when I build the same exact blueprint in UE4, it works in the IDE just fine, but when compiled to an .exe the Niagara systems stop reacting to the audio. Though I don’t receive an error message.

Crash in runnable thread FAsyncLoadingThread

Interestingly, if I select “Package for Distribution” it does compile… though I run into other issues.
