Button on Scene not working when the Scene is instantiated to another Scene

Question

I have an issue where I can’t interact with a button if it’s on an instantiated scene. The button node is on scene_1.tscn, and when loading standalone scene, I am able to interact with the button, but when instantiating scene_1.tscn to another scene, the button does not work. What could be the cause?

a lower part of control node in the whole tree is blocking the input
