Breaking a player's attack mid way through

Help and Feedback Scripting Support
#1

Maybe I’m just overthinking this, but I can’t come up with a method of breaking a players attack if they’re hit midway through their attack.

For example, player 1 and player 2 both hit at ROUGHLY the same time, but player 1’s hit registers before player 2, breaking player 2 into a stun (which should theoretically let player 1 combo player 2, however player 2’s hit never gets cancelled when he gets stunned and hence ALSO stuns player 1 giving them both this moment of broken awkwardness. Check the video I attached to see a slowed down version of what I mean.

Can you show your script? I might be able to help

CLIENT SCRIPT:

function Swing()
	if attacking == false and not blocking and CanAttack and not Player:FindFirstChild("Stun") and Stamina >= 12 then
		attacking = true
		lastAttack = tick()
		Stamina -= 7
		Player.Character.Humanoid.JumpPower = 0
		if sprinting then
			Sprint(false)
		end
		
		if attack == 6 then
			print("6")
			attack = 1
		end
		
		Tool.Handle.slash.PlaybackSpeed = math.random(100, 200)/100
		Tool.Handle.slash:Play()
		Tool.trailblade.Trail.Enabled = true
		camShake:ShakeOnce(3, 5, 0.05, 0.1)
		local Anim = Player.Character:WaitForChild("Humanoid").Animator:LoadAnimation(ReplicatedStorage.Animations:FindFirstChild(tostring(attack)))
		Anim:Play()
		Anim.Stopped:Wait()
		RemoteAttack:FireServer(Tool, attack, Anim.Length)
		attack += 1
		attacking = false
		Player.Character.Humanoid.JumpPower = 50
		Tool.trailblade.Trail.Enabled = false
		
		if attack == 6 then 
			CanAttack = false
			wait(Tool.Cooldown.Value)
			CanAttack = true
		end
		
	end
end

server side:

RemoteAttack.OnServerEvent:Connect(function(plr, tool, combo, length)
	coroutine.resume(coroutine.create(function()
		local char = plr.Character
		local hrp = char.HumanoidRootPart
		local Hitbox = RayCaster:Initialize(tool, {char})
		
		Hitbox:DebugMode()
		Hitbox:HitStart()
		
		Hitbox.OnHit:Connect(function(hit, humanoid)
			local player = game:GetService("Players"):GetPlayerFromCharacter(humanoid.Parent)
			if player.IsBlocking.Value == true then
				print("plr blocking!")
				blockeffect(humanoid)
			elseif player.IsParrying.Value == true then
				blockeffect(humanoid)
				stun(plr.Character.Humanoid)
			else
				if combo == 5 then
					Knockback(hit, plr.Character)
					game:GetService("ReplicatedStorage").Remotes.Knock:FireClient(player)
				end
				tool.Handle.hit:Play()
				humanoid:TakeDamage(tool.Damage.Value)
				stun(humanoid)
			end
			Hitbox:HitStop()
		end)
		wait(length - 0.1)
		Hitbox:HitStop()
	end))
end)

also might be good to note i’m using raycast hitbox found here:
