Seem to be happening when the pixiContainer of the layer is destroyed https://github.com/4ian/GDevelop/blob/master/newIDE/app/src/InstancesEditor/InstancesRenderer/LayerRenderer.js#L775

Pixi's container being destroyed tries to remove all children https://github.com/pixijs/pixijs/blob/c04c09c50874fef9296555af23e25fe58cc808a9/packages/display/src/Container.ts#L363

And when an object is being removed, it tries to remove it from its parent: https://github.com/pixijs/pixijs/blob/c04c09c50874fef9296555af23e25fe58cc808a9/packages/display/src/DisplayObject.ts#L665

This is really confusing, as Pixi has a check on wether the parent exists, so it seems that the parent is there, but does not have a method removeChild()
