Describe the bypass and how to replicate it

@eventhandler
public void onSendPacket(PacketEvent.Send event) {
if ((!MovementUtility.isMoving() || inMove.getValue())
&& event.getPacket() instanceof PlayerInteractEntityC2SPacket
&& getInteractType(event.getPacket()) == Criticals.InteractType.ATTACK
&& !(getEntity(event.getPacket()) instanceof EndCrystalEntity)
&& getEntity(event.getPacket()) instanceof LivingEntity lent
&& lent.hurtTime <= hurtTime.getValue()
&& MathUtility.random(0, 100) >= (100 - chance.getValue())
&& !canCrit()) {

        if (mc.player.isSprinting()) sendPacket(new ClientCommandC2SPacket(mc.player, ClientCommandC2SPacket.Mode.STOP_SPRINTING));
        sendPacket(new ClientCommandC2SPacket(mc.player, ClientCommandC2SPacket.Mode.START_SPRINTING));
        sendPacket(new ClientCommandC2SPacket(mc.player, ClientCommandC2SPacket.Mode.STOP_SPRINTING));
        sendPacket(new ClientCommandC2SPacket(mc.player, ClientCommandC2SPacket.Mode.START_SPRINTING));
        debug("wtap");

        mc.player.lastSprinting = true;

The code you provided above is only supposed to actually run when you're sprinting though no?

Dbbtop commented

this function sends a sprint packet to make a pushback attack even without movement
