That’s a lot of code, and Claude cannot fix poor variable naming choices. Next time, instead of using an LLM, I recommend you run your code through a formatter like the one in Godot GDScript Toolkit. It won’t fix short non-descriptive variable names, but it will deal with odd spacing issues and not put annoying comment breaks with no info before each function.
Your problem is most likely that you are using DirAccess. When you export, all those filenames are changed. I recommend taking a look at the solution here in this thread: Image and Audio Files not Loading on Export
That should be enough for you and Claude to figure it out.
EDIT: Also, you posted this in the General section. It should be in Help.
