What is causing crash after memory leak?

How come when my WPF application leaks unmanaged memory and I close it immediately, nothing special happens. But when it leaks unmanaged memory and I leave it sitting for 1 hour (not touching the computer at all) and then I close it, it will crash with an out of memory exception on the Form.Close() call? (while debugging)

It's not because leaked memory has accumulated. It happens even with a little bit of leaked memory.

I want to speed up the process causing this, so that I don't have to sit around for hours while debugging a memory leak trying if it still happens.

Example causing a memory leak:

[DllImport("user32.dll", SetLastError = true)]
  private static extern IntPtr LoadImage(
      IntPtr hInstance,
      string name,
      uint type,
      int width,
      int height,
      uint load);

      IntPtr hIcon = LoadImage(
          IntPtr.Zero,
          iconPath,
          IMAGE_ICON,
          32,
          32,
          LR_LOADFROMFILE | LR_DEFAULTSIZE);

I'm talking .NET 6 here, but I suspect it applies to other versions too.
