Small and probably easy to fix issue with destroying an instance

Im making a rogue game. I made a simple script that creates a hitbox for punches. The problem is that I can’t make it to not spawn at all if “hit” (other players or npc’s) is abscent.

Here’s the local script part of the punch:

--//click
script.Parent.Activated:Connect(function()
	if canPunch and char:WaitForChild("movement"):WaitForChild("isSliding").Value == false and toolequipped then
		canPunch = false
		count = (count%#pAnims)+1
		local Animation = animator:LoadAnimation(pAnims[count])
		Animation:Play()
		wait(0.2)
		--//hitbox
		
		local hitbox = Instance.new("Part")
		hitbox.Transparency = 0.5
		hitbox.Color =Color3.new(1, 0, 0)
		hitbox.Anchored = false
		hitbox.Parent = plr.Character
		hitbox.Name = "fistHitbox"
		hitbox.CFrame = CFrame.new(plr.Character:WaitForChild("HumanoidRootPart").Position)
		hitbox.Size = Vector3.new(3,3,2.2)
		hitbox.CanCollide = false

		local weld = Instance.new("Weld")
		weld.Parent = hitbox
		weld.Part0 = hitbox
		weld.Part1 = plr.Character:WaitForChild("HumanoidRootPart")
		weld.C0 = CFrame.new(0,0,hitboxDistance)
		
		hitbox.Touched:Connect(function(hit)
			if hit and hit.Parent ~= char then
				rEvent:FireServer(hit, dmg)
				hitbox:Destroy()
			else
				hitbox:Destroy()
			end
		end)
		
		
		wait(.6)
		canPunch = true
	end
end)

And here’s the server script:

game:GetService("ReplicatedStorage"):WaitForChild("RMEV"):WaitForChild("Combat").OnServerEvent:Connect(function(plr, hit, dmg)
	hit.Parent.Humanoid:TakeDamage(dmg)
end)

I believe the fix is incredibly simple and I just made a dumb mistake, but I can’t fix this issue for 2 days now.

Fixed the issue by completely remaking combat and changing hit registration method because no one seems to care.
