Error Launching UE4 via Visual Studio 2019

Hi there,

I’ve used the Github repository for UE4 4.26.1 and Git bashed the code. I’ve gone through the first build via Visual Studio and it worked. However I closed the program and every time I now try and use Local Windows Debugger the build keeps cutting out and I get this code below from Visual Studio (I’ve attached the full output from Visual Studio to this post).

If anyone knows what is causing this and a fix, I would be immensely grateful!

FYI - I’m trying to use this tutorial : How To Make A Multiplayer Game With Unreal Engine and Amazon GameLift (Part 1 - UE4 Source) - YouTube, although the only difference is that I’m using the latest Unreal Studio.

Thanks,
