How can I prevent the variables from being initialized upon the first login after closing the window

I used some variables in the system, hoping that these variables can be used to store individual player information and restore them the next time they return to the game.

Currently, the data can be saved, but after closing the window, the variables are initialized upon the first login (I had originally set some default initial values for each new player). However, after that, the situation returns to normal. Does anyone know how to solve this issue?

Here are the initial values of the system variables I set

You need to use the LocalStorage
