Unity New Input System on Android not receive touch event after execute time consuming function

this is demo vedio https://www.youtube.com/watch?v=2YeNwtXaC_0, the project is the New Input System Demo:Touch Sample I add a time consuming function:

 public void DelayTime()
     {
         Stopwatch stopwatch = new Stopwatch();
         stopwatch.Start();
         while (stopwatch.ElapsedTicks < 10000000)
         {
             var vector3 = new Vector3(1.0254452f, 1544.454f, 846.2342412f);
             var magnitude = vector3.magnitude + vector3.sqrMagnitude;
             magnitude += Vector3.Angle(Random.insideUnitSphere, Random.insideUnitSphere);
         }
         stopwatch.Stop();
     }

When click the button,this function will be called.

The problem is when click the button one or more times,means android will freeze .When android freeze,I touch the screen a little times,and then the screen will never receive touch event from new input system.
