This discussion is about my problem with recreating the game SuperHot and encountering an error in the running of the game

You rewind tutorial, and follow it again step by step.

You are watching that tutorial to learn, so learn it and understand what does what.

Then you will know where code responsible for that is, and then you can rewind tut again and see what you did differently from tut.

For making games you need to learn that stuff (and understand it) anyway, so start now.
