PROBLEM My script has a problem where if there is 2 or more players in the game, if one player transforms, the other cannot and gets somewhat "stuck" and cannot transform without resetting, I am confused and do not know how to fix this.

LOCAL SCRIPT

-- player
local Player = game.Players.LocalPlayer
local Character = Player.Character
repeat wait() until Player or Character ~= nil

-- input
local UIS = game:GetService("UserInputService")

-- variables
local CanChange = true
local InTransformation = false
local RemoteEvents = game.ReplicatedStorage.RemoteEvents

--{{ tranformation }}--
UIS.InputBegan:Connect(function(input, gpe)
	if input.KeyCode ~= Enum.KeyCode.Z then return end;
	if gpe then return end;
	if CanChange == true then
		CanChange = false
		if InTransformation == true then return end;
		if InTransformation == false then
			print("DEBUG MSG: Super Saiyan Transformation")
			
			-- remotevent
			RemoteEvents.Transformations.TransformSSJEvent:FireServer()
			
			InTransformation = true
		end
		print("DEBUG MSG: Script Got to wait")
		wait(5)
		CanChange = true
		print("DEBUG MSG: Script Finished Wait")
	end
end)


--{{ deformation }}--
UIS.InputBegan:Connect(function(input, gpe)
	if input.KeyCode ~= Enum.KeyCode.X then return end;
	if gpe then return end;
	if CanChange == true then
		CanChange = false
		if InTransformation == false then return end;
		if InTransformation == true then
			print("DEBUG MSG: Reverted back to base")
			
			--remoteevent
			RemoteEvents.Transformations.DeformSSJEvent:FireServer()
			
			InTransformation = false
		end
		print("DEBUG MSG: Script got to wait")
		wait(5)
		CanChange = true
		print("DEBUG MSG: Script finished wait")
	end
end)

	if inSSJ == true then

		-- remove power boosts
		
		inSSJ = false
	end
end)

FINAL THOUGHTS Please excuse me for the long script.
