Line 363 is empty in your paste above 😂

Anyway most likely npe comes from

  InstanceWorld world = InstanceManager.getInstance().getPlayerWorld(player)

You will have to debug why it's null

i don't know what i can do now, how i can fix that. I don't know how to debug it.

Fixed. Thank's to @An4rchy
