the dog shows up when you fail to connect to the internet when the game launches, it has to connect to the internet in order to update the patron list so when it fails it for some reason triggers that dog to appear as for the black screen i have no clue
Black screen is most likely caused by a resolution error. This is a shot in the dark so it probably wont work, but me and my friend were able to fix this by doing the following...
>Stream your game to a friend (through discord or otherwise) >Have them guide you where to move your mouse >Work together to navigate to settings>render>resolution >Select your resolution >Click apply
