Unreal 4 Game on Steam doesn't work with Win11

Awesome, let me know how it goes. If you can find any reasons for the outright quit we might be able to point at the issue a bit better.

In the meantime, I’d also try forcing the game in windowed mode for the testing as well. There is a known issues with Win11 and older (DX 10) builds that would cause DX Device disconnection errors, though they aren’t usually without a crash notify.
