I get the error "Invalid access to property or key 'position' on a base object of type 'null instance'." even though its in _ready()

so im randomly trying out my code after 3 hours of not updating it and i SUDDENLY get this error.
“Invalid access to property or key ‘position’ on a base object of type ‘null instance’.”
i checked and everything is in a _ready() or @orneady.
so i dont really understand the problem.

any help is appreciated!
