I have 3 map and ı was buil all of them before packaging but again I meet this problem. Anyone knows it ?
I have had a same issue. Try running your game with “-dx12” parameter. You can do it by creating shortcut to your game exe file, and then right click - properties, and in target, at the end add space and -dx12. So it will look something like this: {path_to_your_exe}.your_game.exe -dx12
I hope there is some other solution thought
