MouseHook stops sending input randomaly

I have a MouseHook class that I got, And I created an event with it, but it's randomly stopping sending input to the event for some reason, Its sending the location/buttons for a couple of seconds to minutes but for some reason it just stops randomly

I created and event like that

MouseHook mouse = new MouseHook();
mouse.OnMouseActivity += new System.Windows.Forms.MouseEventHandler(Mouse_OnMouseActivity);
mouse.Start();

And that's how I notice (For some reasong after couple of seconds-minutes it just stops sending input)

 void Mouse_OnMouseActivity(object sender, System.Windows.Forms.MouseEventArgs e)
    {
        num++;
        Console.WriteLine(num);


        
    }

and that's the class:

public class MouseHook
{
    private const int WM_MOUSEMOVE = 0x200;
    private const int WM_LBUTTONDOWN = 0x201;
    private const int WM_RBUTTONDOWN = 0x204;
    private const int WM_MBUTTONDOWN = 0x207;
    private const int WM_LBUTTONUP = 0x202;
    private const int WM_RBUTTONUP = 0x205;
    private const int WM_MBUTTONUP = 0x208;
    private const int WM_LBUTTONDBLCLK = 0x203;
    private const int WM_RBUTTONDBLCLK = 0x206;
    private const int WM_MBUTTONDBLCLK = 0x209;
