How to make a part appear, disappear and then reappear again?

So, before I was trying to make a part appear in the workspace and then disappear. It clearly didn't work before but now it does (thanks to moo1210 for explaining it to me). But now, I want to make the part reappear again after it destroyed itself from the workspace. It didn't work, instead it gives me an error saying, " 13:55:55.919 - The Parent property of JumpBoost is locked, current parent: NULL, new parent Workspace". Here's my script (it is located in the ServerScriptService):

local jumpBoost = game.ReplicatedStorage:FindFirstChild("JumpBoost")
local clonedJumpBoost = jumpBoost:Clone()
clonedJumpBoost.Parent = workspace
local boostedJumpPower = 100
local function onPartTouch(otherPart)
	local partParent = otherPart.Parent
	local humanoid = partParent:FindFirstChildWhichIsA("Humanoid")
	if ( humanoid ) then
		clonedJumpBoost.CanCollide = false
		local currentJumpPower = humanoid.JumpPower
		if currentJumpPower < boostedJumpPower then
			humanoid.JumpPower = boostedJumpPower
			clonedJumpBoost:Destroy()
			wait(5)
			if clonedJumpBoost.Parent ~= workspace then
				clonedJumpBoost.Parent = workspace
			end
			humanoid.JumpPower = currentJumpPower
		end
	end
end
clonedJumpBoost.Touched:Connect(onPartTouch)

Repeatedly eliminating an instance will cause it’s Parent to lock, if you’re destroying more than one descendant of a Parent at once or the same multiple times, it will lead to this event, switch to :Remove() or switching the form of your statement:

workspace:WaitForChild("JumpBoost"):Destroy()

This problem could also just be accustom to the Server it’s running in, this could be solved if you save your code, quit Studio, reopen, and put your Script back in. ROBLOX has been having quite a few Engine issues lately

So, I followed your advice @simplealgorithm but it still didn't work and it gives me the same error. Here's my script:

local jumpBoost = game.ReplicatedStorage:FindFirstChild("JumpBoost")
local clonedJumpBoost = jumpBoost:Clone()
clonedJumpBoost.Parent = workspace
local boostedJumpPower = 100
local function onPartTouch(otherPart)
    local partParent = otherPart.Parent
    local humanoid = partParent:FindFirstChildWhichIsA("Humanoid")
    if ( humanoid ) then
        clonedJumpBoost.CanCollide = false
        local currentJumpPower = humanoid.JumpPower
        if currentJumpPower < boostedJumpPower then
            humanoid.JumpPower = boostedJumpPower
            workspace:WaitForChild("JumpBoost"):Destroy()
            wait(5)
            if clonedJumpBoost.Parent ~= workspace then
                clonedJumpBoost.Parent = workspace
            end
            humanoid.JumpPower = currentJumpPower
        end
    end
end
clonedJumpBoost.Touched:Connect(onPartTouch)

Also, I tried using :Remove(), fortunately, it did remove the part and put it back in the workspace, however, the part didn't seem to disappear when I step on it anymore and it also didn't give me a jumpboost. Here's the script with the :Remove() function:

local jumpBoost = game.ReplicatedStorage:FindFirstChild("JumpBoost")
local clonedJumpBoost = jumpBoost:Clone()
clonedJumpBoost.Parent = workspace
local boostedJumpPower = 100
local function onPartTouch(otherPart)
    local partParent = otherPart.Parent
    local humanoid = partParent:FindFirstChildWhichIsA("Humanoid")
    if ( humanoid ) then
        clonedJumpBoost.CanCollide = false
        local currentJumpPower = humanoid.JumpPower
        if currentJumpPower < boostedJumpPower then
            humanoid.JumpPower = boostedJumpPower
            clonedJumpBoost:Remove()
            wait(5)
            if clonedJumpBoost.Parent ~= workspace then
                clonedJumpBoost.Parent = workspace
            end
            humanoid.JumpPower = currentJumpPower
        end
    end
end
clonedJumpBoost.Touched:Connect(onPartTouch)
