Laggin problem on the Slider

I have a game that uses Input.GetMouseButton(0) to jump, you jump as you hold Mouse0 and the issue is when i die and reload the game scene the hold slider is starting to lagging. On the second reloading the scene it lagging a bit more than last scene. I think there is a problem with reloading the scene. By the way i reload scenes with SceneManager.LoadScene(int sceneNumber).

This is my game link which can be downloaded on Google Play Store
