When playing on any world or server, the game will completely freeze around one to three times every three or so minutes. This freeze lasts for up to five seconds and freezes the player in the state they were in, even if they were in the air. On multiplayer, other players can still interact with this frozen player, and all knockback inflicted will be stored up until the freeze ends. This bug first appeared when the 1.21.40 update was released.
