OOP with Java: 17. Tetris Game with Java Swing (Part VII. Adding a leaderboard)

In this video, we will make our game a bit more competitive by adding a leaderboard. To display the leaderboard, we will use the JTable component; and to let the user type in their name, we will use of the static methods of the JOptionPane class. We will add a couple more Frame forms to our project and wire them all up into a single multi-form program. In addition, we will further modify our program to make the game restart correctly by terminating the game thread and resetting necessary field.

I am having an issue where my program crashes after I implement all the features up until 5:40. It is telling me that the method "private void drawBlock(Grpahics g)" is throwing a NullPointerException at the line where we instantiate the variable "int h = block.getHeight();". I am not sure exactly why this is happening, since the program seemed to work fine before completing the steps in this video.
Here is what the actual error reads:
"Exception in thread "AWT-EventQueue-0"

smaller issue that I was having that may be related to the problem at hand: I was unable to put JLabels on the right side of the gameAreaPlaceHolder because after running they would display for a half-second in the middle of the gameAreaPlaceHolder and then be completely hidden behind it. So I just moved them to the LEFT side, which seemed to work completely fine. Obviously until now, where I tried performing the steps up until @5:40.

Would anyone have any ideas why this might be happening?
