Assert in packaged development build 4.14.3 - IsInGameThread(), particle component, pausing

What is the right way to upload the project? It uses sample content so it’s 2.5gb ><.

I did figure out what the problem was anyways- the blueprint that called SceneCapture2D->CaptureScene() was set to tick in the Physics tick in our project (and I copied it to the sample project). As soon as I moved it back to prephysics all worked properly.
