Knockback system breaking

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!

A basic knockback system using assembly velocity.

  1. What is the issue? Include screenshots / videos if possible!

For some reason, when both players attack each other, the knockback is so strong that throws the player out of the map. (video below, sorry for low quality)

  1. What solutions have you tried so far?
    I have tried to set some humanoid states and tried to made it so if the server detected hyperarmor it knocks both players in an opposite direction.

This is the code:

local DealDamageKB = function(self, damage, Hum : Humanoid, Knockback, cframe)
	local force = cframe.LookVector * Knockback
	local mass = Hum.RootPart.AssemblyMass

	local RootPart = Hum.RootPart
	local Player = game.Players:FindFirstChild(Hum.Parent.Name) or false
	
	RootPart:SetNetworkOwner(nil)
	
	Hum:SetStateEnabled(Enum.HumanoidStateType.Physics, true)
	Hum:SetStateEnabled(Enum.HumanoidStateType.FallingDown, false)
	Hum:SetStateEnabled(Enum.HumanoidStateType.Freefall, false)

	if RootPart.AssemblyLinearVelocity.Y > 0.9 then
		print("Capped KB")
		force = force * 0.6 -- 0.676196024591872
	end

	Hum:TakeDamage(damage)
	
	RootPart.AssemblyLinearVelocity = Vector3.new(0,0,0)
	RootPart.AssemblyLinearVelocity = mass * force
	
	task.delay(0.1, function()
		Hum:SetStateEnabled(Enum.HumanoidStateType.Physics, false)
	end)
	
	if Player then RootPart:SetNetworkOwner(Player) end
	coroutine.wrap(StunModule.Stun)(Hum, self.Stun)
end

local RandomAnim = function(Hum)
	for i,v in pairs(Hum.Animator:GetPlayingAnimationTracks()) do
		v:Stop() v:Destroy()
	end

	Hum.Animator:LoadAnimation(DamagedAnims[math.random(1, #DamagedAnims:GetChildren())]):Play()
end

module.OnTouch = function(self, Hum, cframe, Action)
	if not Hum or not self.Character then return end
	local EnemyPlayerV = ValuesHandler[Hum.Parent]
	local RootPart = self.Character.HumanoidRootPart
	if not EnemyPlayerV.Loaded then return end

	if EnemyPlayerV.HyperArmor == true then 
		
		local force = cframe.LookVector * -10
		
		local Hum = self.Character.Humanoid		
		local mass = Hum.RootPart.AssemblyMass

		local RootPart = Hum.RootPart
		local Player = game.Players:FindFirstChild(Hum.Parent.Name) or false

		RootPart:SetNetworkOwner(nil)

		Hum:SetStateEnabled(Enum.HumanoidStateType.Physics, true)
		Hum:SetStateEnabled(Enum.HumanoidStateType.FallingDown, false)
		Hum:SetStateEnabled(Enum.HumanoidStateType.Freefall, false)

		if RootPart.AssemblyLinearVelocity.Y > 0.9 then
			print("Capped KB")
			force = force * 0.6 -- 0.676196024591872
		end

		RootPart.AssemblyLinearVelocity = Vector3.new(0,0,0)
		RootPart.AssemblyLinearVelocity = mass * force

		task.delay(0.1, function()
			Hum:SetStateEnabled(Enum.HumanoidStateType.Physics, false)
		end)

		if Player then RootPart:SetNetworkOwner(Player) end
		
		return
	end

	if EnemyPlayerV.Blocking.Active then
		if self.BlockBreak then
			EnemyPlayerV.Blocking.Health = 0
			print(EnemyPlayerV.Blocking.Health)
		else
			EnemyPlayerV.Blocking.Health -= 1
			print(EnemyPlayerV.Blocking.Health)
		end
		return
	end
	
	local Knockback = nil
	local Damage = nil

	if Action == "M1" then
		if self.LastM1 then Knockback = self.Knockback.Last else Knockback = self.Knockback.Normal end
		Damage = self.Damage
	else
		Knockback = self.Knockback
		Damage = self.Damage/2
	end

	coroutine.wrap(RandomAnim)(Hum)
	DealDamageKB(self, Damage, Hum, Knockback, cframe)
end
