Crash after loading new scene (Build & Edit Mode)

[alexr4]

Version : Unity3D 2017.1.1f1

Hi,

I'am creating a project where I need to have 3 differents scenes between which I ramdomly change.
In edit mode and build the application seems to crash after a certain amount of loop.
I tried to delay the spout sender creation and the crash seems to come from the spout sender creation (the scene run well during X frames then crash). The crash doesn't seems constant (sometime it happens between just two scenes, sometime after 10 scenes)

Do you have any idea to help us on that issue ?
Maybe there is a way to keep the spout sender between scene ?

Thanks
