Animation Shift to Run Not working with player has jump Already

[static2240 (DevStatic)]

Today I have been trying to figure out why my animation won’t play when the player is running and then jump and then animation stops

Code

local function Handler(actionName, inputState, inputObject)
	if actionName == "Run" then
		if inputState == Enum.UserInputState.Begin then
			Humanoid.WalkSpeed = 50
			RunAnimation:Play()
			Runing = true
		end
		if inputState == Enum.UserInputState.End then
			if RunAnimation.IsPlaying then
				RunAnimation:Stop()
			end
			Humanoid.WalkSpeed = 16
			Runing = false 
			
		end
	end
end


ContextActionService:BindAction("Run",Handler,false, Enum.KeyCode.LeftShift,Enum.KeyCode.RightShift)

 Humanoid.Jumping:Connect(function(isActive)
	if isActive == false and Runing == true then
		RunAnimation:Play()
	end
end)
