Could you show us the full PlayerStateFree script?

First use the code block provided in the forum when posting code. It is on the toolbar and look like </>

Second I assume you are going through a Spaulding tutorial or guide. These guides where written before 2.3 and you will either need to modify them to work with 2.3 or find a 2.3 tutorial.

In general with 2.3 you should not be using script_execute (it can still be used and has a place, but not generally). Instead you need to be calling functions that are declared inside scripts. If you have code outside of a function block in a script then you need to be aware of what scope that code will be run in.

Please review the manual for 2.3 by pressing F1 in the GMS2 IDE; read the sections that cover scripts, functions, objects, instances and variable scope. If you are going to be using an outdated tutorial then you will need to know how to revise it to get it to work. Otherwise, revert back to 2.2.5 and continue to follow the tutorial.

For the current problem. How are you calling this script or function, from which instance, and which events.? Show the whole call stack. Most likely PlayerStateFree is being called from another global script.
