Apparently, built-in player movement is controlled with PlayerModule which is said to be located at StarterPlayer\StarterPlayerScripts\PlayerModule but is nowhere to be seen. I don't see it on the player when they are spawned in either.
Play in studio and it should be inside the Player. If you want to edit it you have to copy the script from the play in studio and paste it into StarterPlayer.StarterPlayerScripts
