Fatal Error! Crash in runnable thread AudioThread in packaged game

Development Platform & Builds

Sorry if this is in the wrong category.

In engine, the game starts up fine with no errors, but in a build the game will crash and give a fatal error. It says it’s an issue with AudioThread, but I don’t know what could be causing it.
Even stranger, it only seems to happen one time, as once the crash happens if you start the game again it usually doesn’t happen again. It also seems to happen if there’s no save data in appdata, which is also weird.

I’m on UE4 4.27.2.
If anyone has any ideas or suggestions they’d be much appreciated:

Crash in runnable thread AudioThread

Not sure if you are having the same issue as me but I was also getting a crash due to the audio thread. Turned out to be a niagara system using the audio visualiser. Try going in to project settings and turn off ‘async loading thread enabled’ and see if that does anything. If that works might be worth trying to find any offending niagara systems

We haven’t used Niagara at all afaik, however it is enabled in the project plugins. I can try disabling it and see if that does anything. Aync Loading Thread is disabled in my project settings.

Ahh ok, was just a shot in the dark really. Hope you work out what it is

Thanks for the suggestion anyway, help is always appreciated

If anyone sees this thread, check if you have I/O store enabled in your packaging settings. We were using Oodle for our compression, but apparently Oodle doesn’t like I/O store and it can cause issues. Disabling I/O store fixed the issue for me.
