I have a UI bug that I can not figure out. I wish to be able to carry my score over into each scene, while also having each scene independent of one another. If the player chooses to start the game in level 6 he should be able to do so with a clean scoreboard, same as starting at level 1. The score should proceed unitl to transfer until the player dies at which point the score should be set back to 0. To do this I've prefabbed my scoreboard and dropped it into every scene using the singleton pattern to make sure that there are no duplicate scoreboards in the scene. While trying to access my score text UI of type Text using UnityEngine.UI I receive a null reference error when the class is called after loading a new scene. Here are the C# classes defining the methods used in order to implement the functionality and screes snippets of my hierarchy in Unity 2019.4.1f1. I'm also attaching a short youtube video to show you that the score does work in the first scene, however it does not work in any other scene after. I do know that I'm destroying the Text UI at the beginning of every scene if there are multiple. What I do not understand is why the Text UI nested under the Scoreboard Canvas is not finding it's reference on Awake() for every instance created and why it's being called null. I truly appreciate anyone help!

Here are the screen snippets and videos in this order:

1. Youtube video of bug
2. Hierarchy of Scoreboard Canvas
3. Hierarchy of Score Text
4. Scoreboard singleton class (Attached to Scoreboard Canvas)/ ScoreText class (Attached to ScoreText UI)
5. Implementation of classes used to add score upon completion of level in CollisionHandler class
