Unreal Engine crashes on mobile RTX2080

Hi im experiencing UE4 crash after 1-5 minutes of working, but when Unreal application is open on external monitor, everything works perfect, no crashes. I have tested it many times the crash occurs when working with only laptop screen. So basically i always need to find an external monitor wherever i go its really frustrating. How can this be fixed?

In your Nvidia Control Panel go to 3D settings and set the Nvidia GPU to be the global default GPU rather than the Intel GPU

Didnt work, problem still there

Also check your power settings and make sure it’s not set to some power saving mode

Hi i always set everything to the max also checked the power saving mode
