I am new to the thread, and I am pretty much in the same spot some of you are with porting from UE4 to XboxOne through UWP Deployment, where basically, the game crashes at the splash screen after running the in developer mode on the XboxOne. The game I am running utilizes far less than 1GB of memory, and is quite small so I am pretty sure it is not a matter of the application exceeding available resources…
I haven’t tested the UWP build uploaded today 8/11, but willing to give it another shot with that hopefully within the next day, I can certainly report my results once done as well.
