Editor crash at shutdown when using Engine::get_singleton()

[jacogasp]

Hello,
I don't know if the following is related to this open issue, but when I try to simply access the Engine singleton in one on my Node2D class in GDExtension, this makes the editor crash at shutdown.

Example

void _physics_process(float delta) {
  auto const engine = Engine::get_singleton();
  if (engine->is_editor_hint()) {
    return;
  }
}

Just calling Engine::get_singleton(); is sufficient to make the issue to show up.
Invoking Godot from terminal with godot --editor gives the following trace at shutdown
