For those having an issue with black screen try updating your GPU drivers to the latest one if you have not already done so.
I remember being in a situation where Windows installs a driver for GPU and it stays on that older version which would cause the black screen issue (yes, it was on the same engine as this game project). The point is - update manually to the latest revision from AMD/Nvidia/Intel websites for your GPU model.

And about the "NTR" complaints. Games are a work of fiction and not real life, right? Riiiigghhtt?? And in this particular case, as dev had said, currently there is no content of that type and if there is in the future it would be easily avoidable. The banner is used to showcase the new scene and will probably get changed as even newer content gets added.
But why are you projecting your irl insecurities over a piece of ficiton? I mean I could understand since the lines between technology and real life get blurred more and more. For example let's say that there was a true adults only version of something like VRChat and you get to experience the "real" cucking on there and yeah it is understandable to get upset. Since the lines got blured and all.
But almost all of the classic video games are not that. And this means the issue is self-projection in the game world. I think most of the time you are not supposed to self-insert but rather enjoy the story of the already defined characters. Unless there is a "make your own character" feature.
If you do not like a particual content such as NTR then that simply means you are not the target audience. It is impossible to please the majority.
