Hi, I am replying from my other account. It was a bug solved in Godot 4.2 related to change_scene. If you can't upgrade, the way to fix it is to avoid using the built-in change_scene and instead have a main scene with a parent Node and your current scene as a child. When you change scene, you delete the child normally and then swap it with the newly loaded scene that should replace it. This solved the issue in Godot 4.0 for me!
Please do note that this bug ONLY happens in release versions and NOT in Debug/in-editor versions!
