Problem with scene dialogue?

Hello, I founded an issue working on a project.
When I preview one of the scene, the game tells me a crash or error happened in my game

To Reproduce

  • load the JSON for dialogue
  • tell to start from branch X
  • preview and tell me something wrong

Other Details

  • Desktop version 5.3.186
  • Had the same code for other scene, did not crashed
  • Looks like it’s because of the JSON file of this scene (but I’m not too sure)
