change $Player.start($StartPosition.position) to
$Player.Start($StartPosition.position)

This is not the correct fix for GDScript code, which uses the snake_case naming convention for method names. Notice how the line just below uses start().

If it doesn't work locally, double-check that you defined the player's start function as start() and not Start().
