Thanks, we’ll also need to know your FMOD version to look up the appropriate symbols to read the crash stack.

Sure thing:
FMOD: 2.01.11
Unity: 2020.3.17f1

Thanks, it looks like your code is calling `FMOD::Studio::EventInstance::setUserData` before the System has been created, can you check if any of your scripts are calling into that API and when that’s happening?

Our game has a “preload” scene that instantiates a bunch of stuff before loading the actual game. Nowhere in that scene do we call setUserData and the android build never gets to load another scene before this crash so I don’t think it’s something we’re calling. Also, it only seems to be happening on android.

Could you try doing a full search for “setUserData” in all scripts, including FMOD scripts. I’ve done the same here and I cannot find anywhere we call that API as part of the integration. If that comes up with nothing I suspect the crash trace is playing tricks on us and I’ll need to make the debug symbols available to you to try and get a better crash stack.

Hey Mathew, thanks for taking a look into this. I totally messed up. I didn’t realize we had a static initializer that was calling those methods. For whatever reason, everything works on all platforms except Android. I’m not sure why that is, but I’ve fixed the problem and it’s working now.
Sorry to take up your time, and thanks again!

No worries, I’m glad you were able to get to the bottom of it.
The reason it might be different on Android vs other platforms is because on Android the FMOD code is split over two binaries. Where other platforms are implemented as just one. The code that was crashing was something from libfmodstudio that gets initialized in libfmod via Studio::systemCreate.

Ahhh that makes sense to me. Thanks for explaining!
