Check you laptop charging cables and ports guys. I had a similar issue when I had my P.O.S. Razer Blade (Never buying Razer again, but that’s a story for another day.)
Most laptops with discrete graphics will auto-switch to the built-in Intel gpu when it switches to battery. Unreal doesn’t know what to do, and so therefore it crashes.
If not that check you’re GPU TDR Delay. If you’re doing stuff with a lot of info or computation, the default TDR delay might cause the driver to stop responding and therefore crash.
You can find quick info on the first post of this thread just prior to the change log: https://forums.unrealengine.com/deve…ss?view=thread
Hopefully this helps
